Mitochondrial disease v0.212 TIMMDC1 Bryony Thompson gene: TIMMDC1 was added
gene: TIMMDC1 was added to Mitochondrial disease. Sources: NHS GMS
Mode of inheritance for gene: TIMMDC1 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: TIMMDC1 were set to 28604674; 30981218
Phenotypes for gene: TIMMDC1 were set to Mitochondrial complex I deficiency, nuclear type 31 MIM#618251
Review for gene: TIMMDC1 was set to AMBER
Added comment: A deep intronic variant (c.597-1340A>G, only detectable by WGS) that causes a splicing aberration was identified in a homozygous state in 3 unrelated cases from different ethnic backgrounds. A patient with Leigh-like syndrome had a homozygous stopgain variant in PDHX and a homozygous stopgain variant in TIMMDC1 (p.Arg225*). The TIMMDC1 mutant protein could still rescue complex I assembly in TIMMDC1 knockout cells and the patient’s clinical phenotype was not clearly distinct from that of other patients with the same PDHX defect.
