Methylmalonic aciduria and homocystinuria, cobalamin C (CblC) disease (OMIM 277400), is the most frequent inborn error of vitamin B12 (cobalamin, Cbl) metabolism and is caused by an inability of the cell to convert Cbl to its active forms (MeCbl and AdoCbl). More than 75 mutations have been identified in the MMACHC gene which is responsible for CblC disease. We present a case with CblC disease and pulmonary arterial hypertension (PAH) as the main symptom. The patient improved dramatically with parenteral hydroxocobalamin treatment. Most cases of CblC disease have a multisystemic disease with failure to thrive, developmental delay, hypotonia, visual impairment, and hematologic manifestations. This patient had isolated pulmonary hypertension and hyperhomocysteinemia which is thought to be an important factor in the pathogenesis of PAH. Genetic analysis identified a novel homozygous mutation (c.484G > T; p.Gly162Trp) in the MMACHC gene. Conclusion: CblC disease should be considered in the differential diagnosis of pulmonary hypertension. © 2014, Springer-Verlag Berlin Heidelberg. Source

We report an 11-year-old female with 7q11.23 microduplication detected by an array-CGH test performed because of her atypical facial appearance while being followed-up with diagnoses of epilepsy and cerebral palsy at the pediatric neurology department since she was 3 months old. We emphasize that the facial phenotype by itself should arise suspicion of the 7q11.23 duplication. Source

Isolated adrenocorticotropic hormone deficiency is a rare cause of adrenocortical insufficiency, especially in children, and may be an underestimated cause of neonatal death. Low estriol levels are usually correlated with compromised uteroplacental perfusion and associated with fetal death. A 30-years old woman applied for pregnancy follow-up. Ultrasonographic evaluation and karyotype of the fetus are normal. Low estriol level 0.34 MoM (% 0.24) was detected in maternal triple screening test. Amniocentesis was performed, and chromosomal disorders, steroid sulfatase deficiency, and Smith-Lemli-Opitz syndrome (SLOS) were excluded with karyotype, fluorescence in situ hybridization (FISH), and molecular analysis of SLOS, respectively. As their first child had pro-opiomelanocortin (POMC) deficiency, POMC gene analysis was performed from both amniotic fluid and ethylene diamine tetra aceticacid (EDTA) blood sample of affected previous child, and homozygote mutation was detected. Fetus is diagnosed as POMC deficiency. We are presenting this case to discuss possible relationship of low maternal E3 levels and fetal POMC deficiency. © 2013 John Wiley & Sons, Ltd. Source

Objective: To determine the frequency, types of chromosomal abnormalities and Y chromosome microdeletions in patients with severe male factor infertility, and the association between clinical background and genetic abnormality. Study design: A total of 322 infertile men; 136 men with severe oligozoospermia (sperm count <5 million/ml) and 196 with nonobstructive azoospermia were studied between April 2004 and November 2006 at the Dr. Zekai Tahir Burak Women's Health Education and Research Hospital, Ankara, Turkey. Blood, semen samples, and testicular biopsies of patients were obtained. Hormonal analysis (follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels), semen analysis, karyotype analysis, and PCR screening for Y chromosome microdeletions were performed. Result(s): Forty-eight out of 332 (14%) infertile men had a genetic abnormality. Twenty-four (7.2%) cases with karyotype abnormality were detected. The frequencies of karyotype abnormalities were Klinefelter's syndrome 17/24 (71%), translocation 3/24 (12%), mix gonadal dysgenesis 2/24 (8%), XX male 1/24 (4%), and 46XYY 1/24 (4%). Twenty cases (6%) infertile men had only Y chromosome microdeletions. The frequencies of the deleted areas were azoospermia factor (AZF)c 42%, AZFb 25%, AZFa 21%, AZFb, c 8%, and AZFa, c 4%. Four of the cases with Y chromosome microdeletions also had a concurrent karyotype abnormality. Conclusion(s): All patients with nonobstructive azoospermia and severe oligozoospermia (sperm count <5 million/ml) should undergo genetic screening. © 2012 The British Fertility Society. Source

Purpose: Coffin-Lowry syndrome (CLS) is a rare X-linked semidominant syndromic genetic disorder that is characterized by typical facial and radiologic findings, psychomotor and growth retardation, and various skeletal anomalies. A distinctive paroxysmal disorder called stimulus-bound myoclonus is clinically heterogeneous and is generally characterized by a sudden loss of muscle tone that is regained within a few seconds and is induced by sudden auditory or tactile stimulus. As the pathophysiology of stimulus-induced drop episodes (SIDEs) is not well understood, there is no definite therapy for those episodes. Methods: We report a 15-year-old female with stimulus-induced drop episodes occurring many times a day that resulted in failure to perform her daily activities. Because her SIDEs were misdiagnosed as atonic seizures, she was treated with several antiepileptic drugs, including valproic acid, levetiracetam, lamotrigine, primidone, carbamazepine, and clobazam. Results: We realized that her clinical and radiological findings, together with SIDEs, are compatible with Coffin-Lowry syndrome. All of her medications were discontinued following the diagnosis of SIDE, and she was started on clonazepam. After treatment, she became more independent and was able to perform her daily activities. Subsequently, her episodes decreased from 3 times a day to 1-2 times a month. Sodium oxybate and fluoxetine were added to the treatment protocol without remarkable improvement. Her genetic analysis revealed a heterozygous variation of CLS. Conclusion: We conclude that SIDE should be included in a differential diagnosis of epileptic seizures in patients with CLS and that clonazepam is an effective choice in the treatment of SIDEs. © 2014.
