Zornitza Stark edited their review of gene: PMM2: Added comment: Association with HIPKD: Cabezas et al (2017) reported co-occurrence of hyperinsulinaemic hypoglycaemia and polycystic kidney disease (HIPKD in 17 children from 11 unrelated families. Patients presented with hyperinsulinaemic hypoglycaemia in infancy and enlarged kidneys with multiple kidney cysts. Some progressed to ESKD and some had liver cysts. Whole-genome linkage analysis in 5 informative families identified a single significant locus on chromosome 16p13.2. Sequencing of the coding regions of all linked genes failed to identify biallelic mutations. Instead, they found in all patients a promoter mutation (c.-167G>T) in PMM2, either homozygous or in trans with PMM2 coding mutations. They found deglycosylation in cultured pancreatic β cells altered insulin secretion. In vitro, the PMM2 promoter mutation associated with decreased transcriptional activity in patient kidney cells and impaired binding of the transcription factor ZNF143. In silico analysis suggested an important role of ZNF143 for the formation of a chromatin loop including PMM2. They proposed that the PMM2 promoter mutation alters tissue-specific chromatin loop formation, with consequent organ-specific deficiency of PMM2 leading to the restricted phenotype of HIPKD. None of the patients exhibited the typical clinical or diagnostic features of CDG1A. Serum transferrin glycosylation was normal in 11 patients who had assessment.; Changed publications: 28108845, 28373276, 32595772; Changed phenotypes: Congenital disorder of glycosylation, type Ia (MIM#212065), Hyperinsulinaemic Hypoglycaemia and Polycystic Kidney Disease (HIPKD), MONDO:0020642, PMM2-related |
