Background: Hypoparathyroidism, deafness and renal dysplasia (HDR) syndrome is a rare condition inherited as an autosomal dominant trait. The responsible genetic defect is in the region 10p. Phenotype is very similar to DiGeorge Syndrome (DGS) which occurs due to 22q11 microdeletion.Method: An 8-year-old girl was referred to Pediatric Endocrinology outpatient department because of hypoparathyroidism. She was born at 36 weeks after a normal pregnancy and ...

A Rare Cause of Ovarian Failure; Ovarioleucodystrophy

Sari Erkan , Arslan Mutluay , Yesilkaya Ediz , Vurucu Sebahattin , Kocaoglu Murat , Unal Bulent

Background: Ovarianleucodystrophies are one of the rarest leucodystrophies associated with primary ovarian failure. Patients may present with variable disease manifestations such as neurologic, psychiatric or ovarian failure. Disease onset may occur in infancy, adolescence or adulthood caused by mutation in the eukaryotic initiation factor 2B (eIF2B) which has a poor prognosis.Objective and hypotheses: Seventeen-year-old girl was brought with tremor, gai...

Anik Ahmet , Catli Gonul , Tuhan Hale Unver , Abaci Ayhan , Korkmaz Huseyin Anil , Ozkan Behzat , Sari Erkan , Yesilkaya Ediz , Altincik Ayca , Kizildag Sefa , Bober Ece

Background: MODY is an autosomal dominant inherited type of diabetes with significant genetic heterogeneity. To date, there are mutations in more than ten different genes that result in the MODY phenotype and new mutations causing MODY are still being found.Objective and hypotheses: In this study, we aimed to perform a molecular analysis of pediatric MODY patients by next-generation sequencing which enables the simultaneous analysis of multiple genes in ...
