BOSTON--(BUSINESS WIRE)--Today, FDNA (www.FDNA.com) announces its collaboration with two of the most reputable genomics testing labs in the world, GeneDx and Blueprint Genetics. The collaboration will fully integrate FDNA’s analysis into the genetic testing workflow of these labs by enabling clinicians to share phenotypic data with these labs in real time. This marks the first time clinicians will have the ability to send phenotypic data, including facial analysis collected through FDNA’s Face2Gene suite, directly to labs, paving the way for a new precision medicine industry standard. Founded in 2011, FDNA is committed to helping clinicians, labs and researchers diagnose, treat and create therapies for rare diseases. FDNA’s Face2Gene suite of applications helps to quickly evaluate patients’ clinical signs through artificial intelligence and facial analysis. With a comprehensive database of more than 10,000 rare disease syndromes, this new LABS capability is improving the speed and accuracy of a diagnosis for rare disease patients. “Trying to diagnose patients with genetic sequencing is like searching for a pin in a 22,000-needle haystack,” said Dekel Gelbman, CEO of FDNA. “By providing accurate phenotypic and clinical data to the lab directly at the point of genetic interpretation, we are truly realizing the promise of precision medicine. And, with the power of artificial intelligence behind it, clinicians will be pointed toward potential diagnoses that they may have never otherwise considered. GeneDx and Blueprint Genetics are both examples of innovative and renowned labs adopting technology that will lead the way in pinpointing rare disease and promote further medical advancements.” The results of PEDIA, a recent study led by the Berlin Institute of health and Charité University of Medicine, displayed exciting results of this collaboration on the accuracy of genetic sequencing. “We estimate that the addition of phenotypic features [encoded in HPO terms] increases the diagnostic yield to about 60% [from 25% without]. When adding facial analysis, FDNA’s technology, to that process, the diagnostic yield increases to more than 85%,” explained Dr. Peter Krawitz, Principal Investigator of PEDIA. One in 10 people worldwide suffer from a rare genetic disease, and often the search for answers is a tiresome journey. With hundreds of millions of patients having their phenotypic information buried in paper files and unstructured data, it is challenging to integrate this information to support the variant interpretation process. With the Face2Gene LABS application, all of this information is available immediately to support the analysis of genetic testing to help clinicians pinpoint the disease-causing genetic variants as they draw clearer and more efficient conclusions. “This is an important collaboration for several reasons,” said Dr. Ben Solomon, Managing Director of GeneDx and practicing clinical geneticist. “It’s a great way to leverage clinical and genetic information and machine learning approaches to find answers for the clinicians, patients and families GeneDx serves. Aside from providing answers, this integration will make the diagnostic testing process easier, smoother and more enjoyable for clinicians.” “Since 2012, Blueprint Genetics has been developing technological innovations in sequencing and clinical interpretation to improve the quality and performance of rare disease diagnostics,” said Dr. Tero-Pekka Alastalo, PhD and Chief Medical Officer of Blueprint Genetics. “It’s great to see how these innovations are now helping the genetics community and patients suffering from inherited disorders. Combining these technological innovations with our transparent approach to diagnostics and next generation phenotyping tools like Face2Gene represents the next steps forward in molecular genetic diagnostics.” About FDNA and Face2Gene FDNA is the developer of Face2Gene, a clinical suite of phenotyping applications that facilitates comprehensive and precise genetic evaluations.

Purpose:Nevoid basal cell carcinoma syndrome is an autosomal dominant disorder characterized by multiple basal cell carcinomas, jaw cysts, palmar/plantar pits, spine and rib anomalies, and falx cerebri calcification. Current diagnostic criteria are suboptimal when applied to pediatric populations, as most common symptoms often do not begin to appear until teenage years.Methods:We studied minor and major clinical features in 30 children/teenagers and compared the findings with 75 adults from 26 families with nevoid basal cell carcinoma syndrome.Results:Fifty percent of children/teenagers and 82% of adults had at least one basal cell carcinoma. Jaw cysts occurred in 60% of children/teenagers and 81% of adults. Palmar/plantar pits were the most frequent feature seen in affected individuals at all ages. Macrocephaly was seen in 50% of affected and 8% of unaffected children/teenagers. Frontal bossing, hypertelorism, Sprengel deformity, pectus deformity, and cleft lip/palate were seen among affected children/teenagers but not among their unaffected siblings. Falx calcification, the most frequent radiological feature, was present in 37% of individuals <20 and 79% of those >20 years.Conclusion:We report clinical and radiological manifestations of nevoid basal cell carcinoma syndrome in children/teenagers, many of whom lacked major features such as basal cell carcinomas, jaw cysts, and falx calcification. Evaluations for palmar/plantar pits, craniofacial features, and radiological manifestations permit early diagnosis and optimum surveillance.Genet Med 2013:15(1):79-83. © American College of Medical Genetics and Genomics.

Changes in mitochondrial DNA (mtDNA) content in cancers have been reported with controversial results, probably due to small sample size and variable pathological conditions. In this study, mtDNA content in 302 breast tumor/surrounding normal tissue pairs were evaluated and correlated with the clinico-pathological characteristics of tumors. Overall, mtDNA content in tumor tissues is significantly lower than that in the surrounding normal tissues, P < 0.00001. MtDNA content in tumor tissues decreased with increasing tumor size. However, when the tumor is very large (>50cm 3), mtDNA content started to increase. Similarly, mtDNA content decreased from grades 0 and I to grade II tumors, but increased from grade II to grade III tumors. Tumors with somatic mtDNA alterations in coding region have significantly higher mtDNA content than tumors without somatic mtDNA alterations (P < 0.001). Tumors with somatic mtDNA alterations in the D-Loop region have significantly lower mtDNA content (P < 0.001). Patients with both low and high mtDNA content in tumor tissue have significantly higher hazard of death than patients with median levels of mtDNA content. mtDNA content in tumor tissues change with tumor size, grade, and ER/PR status; significant deviation from the median level of mtDNA content is associated with poor survival.

We report five fetuses and a child from three families who shared a phenotype comprising cerebral ventriculomegaly and echogenic kidneys with histopathological findings of congenital nephrosis. The presenting features were greatly elevated maternal serum alpha-fetoprotein (MSAFP) or amniotic fluid alpha-fetoprotein (AFAFP) levels or abnormalities visualized on ultrasound scan during the second trimester of pregnancy. Exome sequencing revealed deleterious sequence variants in Crumbs, Drosophila, Homolog of, 2 (CRB2) consistent with autosomal-recessive inheritance. Two fetuses with cerebral ventriculomegaly and renal microcysts were compound heterozygotes for p.Asn800Lys and p.Trp759Ter, one fetus with renal microcysts was a compound heterozygote for p.Glu643Ala and p.Asn800Lys, and one child with cerebral ventriculomegaly, periventricular heterotopias, echogenic kidneys, and renal failure was homozygous for p.Arg633Trp in CRB2. Examination of the kidneys in one fetus showed tubular cysts at the corticomedullary junction and diffuse effacement of the epithelial foot processes and microvillous transformation of the renal podocytes, findings that were similar to those reported in congenital nephrotic syndrome, Finnish type, that is caused by mutations in nephrin (NPHS1). Loss of function for crb2b and nphs1 in Danio rerio were previously shown to result in loss of the slit diaphragms of the podocytes, leading to the hypothesis that nephrosis develops from an inability to develop a functional glomerular barrier. We conclude that the phenotype associated with CRB2 mutations is pleiotropic and that the condition is an important consideration in the evaluation of high MSAFP/AFAFP where a renal cause is suspected. © 2015 The American Society of Human Genetics.

Recognition of the gene implicated in a Mendelian disorder subsequently leads to an expansion of potential phenotypes associated with mutations in that gene as patients with features beyond the core phenotype are identified by sequencing. Here, we present a young girl with developmental delay, short stature despite a markedly advanced bone age, hypertrichosis without elbow hair, renal anomalies, and dysmorphic facial features, found to have a heterozygous, de novo, intragenic deletion encompassing exons 2-10 of the KMT2A (MLL) gene detected by whole exome sequencing. Heterozygous mutations in this gene were recently demonstrated to cause Wiedemann-Steiner syndrome (OMIM 605130). Importantly, retrospective analysis of this patient's chromosomal microarray revealed decreased copy number of two probes corresponding to exons 2 and 9 of the KMT2A gene, though this result was not reported by the testing laboratory in keeping with standard protocols for reportable size cutoffs for array comparative genomic hybridization. This patient expands the clinical phenotype associated with mutations in KMT2A to include variable patterns of hypertrichosis and a significantly advanced bone age with premature eruption of the secondary dentition despite her growth retardation. This patient also represents the first report of Wiedemann-Steiner syndrome due to an exonic deletion, supporting haploinsufficiency as a causative mechanism. Our patient also illustrates the need for sensitive guidelines for the reporting of chromosomal microarray findings that are below traditional reporting size cutoffs, but that impact exons or other genomic regions of known function. © 2014 Wiley Periodicals, Inc.

Collecting representative sets of cancer microRNAs (miRs) from the literature we show that their corresponding families are enriched in sets of highly interacting miR families. Targeting cancer genes on a statistically significant level, such cancer miR families strongly intervene with signaling pathways that harbor numerous cancer genes. Clustering miR family-specific profiles of pathway intervention, we found that different miR families share similar interaction patterns. Resembling corresponding patterns of cancer miRs families, such interaction patterns may indicate a miR family's potential role in cancer. As we find that the number of targeted cancer genes is a naïve proxy for a cancer miR family, we design a simple method to predict candidate miR families based on gene-specific interaction profiles. Assessing the impact of miR families to distinguish between (non-)cancer genes, we predict a set of 84 potential candidate families, including 75 of initially collected cancer miR families. Further confirming their relevance, predicted cancer miR families are significantly indicated in increasing, non-random numbers of tumor types. © 2012 The Author(s).

We computationally determined miRs that are significantly connected to molecular pathways by utilizing gene expression profiles in different cancer types such as glioblastomas, ovarian and breast cancers. Specifically, we assumed that the knowledge of physical interactions between miRs and genes indicated subsets of important miRs (IM) that significantly contributed to the regression of pathway-specific enrichment scores. Despite the different nature of the considered cancer types, we found strongly overlapping sets of IMs. Furthermore, IMs that were important for many pathways were enriched with literature-curated cancer and differentially expressed miRs. Such sets of IMs also coincided well with clusters of miRs that were experimentally indicated in numerous other cancer types. In particular, we focused on an overlapping set of 99 overall important miRs (OIM) that were found in glioblastomas, ovarian and breast cancers simultaneously. Notably, we observed that interactions between OIMs and leading edge genes of differentially expressed pathways were characterized by considerable changes in their expression correlations. Such gains/losses of miR and gene expression correlation indicated miR/gene pairs that may play a causal role in the underlying cancers.

Despite progress in the determination of miR interactions, their regulatory role in cancer is only beginning to be unraveled. Utilizing gene expression data from 27 glioblastoma samples we found that the mere knowledge of physical interactions between specific mRNAs and miRs can be used to determine associated regulatory interactions, allowing us to identify 626 associated interactions, involving 128 miRs that putatively modulate the expression of 246 mRNAs. Experimentally determining the expression of miRs, we found an over-representation of over(under)-expressed miRs with various predicted mRNA target sequences. Such significantly associated miRs that putatively bind over-expressed genes strongly tend to have binding sites nearby the 3′UTR of the corresponding mRNAs, suggesting that the presence of the miRs near the translation stop site may be a factor in their regulatory ability. Our analysis predicted a significant association between miR-128 and the protein kinase WEE1, which we subsequently validated experimentally by showing that the over-expression of the naturally under-expressed miR-128 in glioma cells resulted in the inhibition of WEE1 in glioblastoma cells.

In response to a call for the global eradication of malaria, drug discovery has recently been extended to identify compounds that prevent the onward transmission of the parasite, which is mediated by Plasmodium falciparum stage V gametocytes. Lately, metabolic activity has been used in vitro as a surrogate for gametocyte viability; however, as gametocytes remain relatively quiescent at this stage, their ability to undergo onward development (gamete formation) may be a better measure of their functional viability. During gamete formation, female gametocytes undergo profound morphological changes and express translationally repressed mRNA. By assessing female gamete cell surface expression of one such repressed protein, Pfs25, as the readout for female gametocyte functional viability, we developed an imaging-based high-throughput screening (HTS) assay to identify transmission-blocking compounds. This assay, designated the P. falciparum female gametocyte activation assay (FGAA), was scaled up to a high-throughput format (Z′ factor, 0.7 ± 0.1) and subsequently validated using a selection of 50 known antimalarials from diverse chemical families. Only a few of these agents showed submicromolar 50% inhibitory concentrations in the assay: thiostrepton, methylene blue, and some endoperoxides. To determine the best conditions for HTS, a robustness test was performed with a selection of the GlaxoSmithKline Tres Cantos Antimalarial Set (TCAMS) and the final screening conditions for this library were determined to be a 2 μM concentration and 48 h of incubation with gametocytes. The P. falciparum FGAA has been proven to be a robust HTS assay faithful to Plasmodium transmission-stage cell biology, and it is an innovative useful tool for antimalarial drug discovery which aims to identify new molecules with transmission-blocking potential.

We describe a first-trimester ultrasound examination in which the finding of fetal encephalocele and the cystic appearance of the kidneys raised suspicion of Meckel-Gruber syndrome (MKS). On the basis of sonographic findings, the patient elected termination of pregnancy, and post-termination studies using next-generation sequencing of a gene panel revealed two mutations (one previously described and the other novel) in the gene CC2D2A. Mutations in CC2D2A are known to cause MKS and Joubert syndrome, thus providing molecular confirmation of the clinical suspicion of MKS and opening the possibility for future prenatal diagnosis. This case highlights the ability to detect important anomalies in the first trimester using ultrasound, even in low-risk situations. It also demonstrates the growing role of new sequencing technologies in fetal testing. Copyright © 2014 ISUOG.
