Chirag Patel gene: TMEM167A was added gene: TMEM167A was added to Genetic Epilepsy. Sources: Literature Mode of inheritance for gene: TMEM167A was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: TMEM167A were set to PMID: 40924476 Phenotypes for gene: TMEM167A were set to Microcephaly, epilepsy, and diabetes syndrome MONDO:0100328, TMEM167A-related Review for gene: TMEM167A was set to GREEN Added comment: 6 individuals from 6 unrelated families (4/6 consanguineous) presenting with neonatal diabetes onset <4mths (6/6), severe microcephaly (6/6), epilepsy (5/6), and developmental delay (4/6). Whole genome sequencing identified biallelic variants in TMEM167A gene. Variants were homozygous in 5/6 families, and variant types were missense (4), frameshift (1), and splice (1), and all variants were rare/unreported in gnomAD. Segregation studies not reported in paper. Microcephaly, epilepsy and diabetes syndrome has 2 known associated genes (IER3IP1 and YIPF5) which encode proteins involved in endoplasmic reticulum to Golgi trafficking. TMEM167A is highly expressed in developing and adult human pancreas and brain. Both TMEM167A depletion in EndoC-βH1 cells and knock‑in of p.Val59Glu variant in iPSC-derived β cells sensitized β cells to ER stress. The p.Val59Glu variant impaired proinsulin trafficking to the Golgi and induced iPSC-β cell dysfunction. Sources: Literature |
