Added new gene as Amber for now, but should be promoted to Green (as there is enough evidence for it to be a Green gene) at the next major review.
PMID: 27640307 describes 5 patients from 5 unrelated families with the same de novo variant (c.1582 C>T, R528W). 3/5 patients have optic atrophy and 2/5 have hypertrophic cardiomyopathy (HCM). The authors have suggested that R528W exerts a dominant negative effect.
Three patients from 2 additional families have biallelic variants (1 compound heterozygous and 1 biallelic deletion of ATAD3B and ATAD3A). These 3 patients did not have optic atrophy nor HCM, but had congenital cataracts.
PMID: 31727539 describes a consanguineous family with 4 affected individuals with biallelic variant (c.1217T>G, L406R). 3/4 had congenital cataracts and 4/4 had HCM. No one had optic atrophy.
