ATAD3C

Chr 1

ATPase family AAA domain containing 3C

The ATAD3C protein is an ATPase that hydrolyzes ATP and is involved in mitochondrial organization. Mutations cause autosomal recessive developmental and epileptic encephalopathy with microcephaly, typically presenting in infancy. This gene shows very low constraint against loss-of-function variants, consistent with recessive inheritance where heterozygous carriers are unaffected.

This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

GOFprediction above median

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
