Comment on list classification: New gene added by Zornitza Stark and an additional Green review from Sara Martins. MECR is associated with a relevant phenotype in OMIM and probably associated with a relevant phenotype in Gene2Phenotype. There is enough evidence for this gene to be Green. Currently, it is rated Amber and will be promoted to Green status at the next major review.Created: 13 Jul 2020, 3:05 p.m. | Last Modified: 13 Jul 2020, 3:05 p.m.

Sara Martins (All Wales Medical Genomics Service)
6 unrelated families, homozygous or compound heterozygous for MECR variants, with optic atrophy and basal ganglia abnormalities. Studies using patient fibroblasts showed that the MECR variants strongly reduced levels of MECR protein and lipoylation compared to controls. It also showed that MECR variants affect, at variable levels, mitochondrial respiratory chain and electron transport system activities (Heimer 2016).Created: 23 Jun 2020, 1:47 p.m. | Last Modified: 23 Jun 2020, 1:47 p.m.
