Ee Ming Wong gene: LETM1 was added gene: LETM1 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: LETM1 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: LETM1 were set to 36055214 Phenotypes for gene: LETM1 were set to Mitochondrial disease MONDO#0044970, LETM1-related Review for gene: LETM1 was set to GREEN gene: LETM1 was marked as current diagnostic Added comment: -18 affected individuals from 11 unrelated families harbouring ultra-rare bi-allelic missense and loss-of-function LETM1 variants -Most of the affected individuals (14/18, 78%) had an infantile-onset disease manifestation, and 4/18 (22%) presented first symptoms between the ages of 1.5 and 2 years -Variant types included missense, frameshift, stop loss, in-frame deletion and splice defect -From biochemical and morphological studies, bi-allelic LETM1 variants are associated with defective mitochondrial K efflux, swollen mitochondrial matrix structures, and loss of important mitochondrial oxidative phosphorylation protein components Sources: Literature |
