Genes affected

ATP6V1A (HGNC:851): (ATPase H+ transporting V1 subunit A) This gene encodes a component of vacuolar ATPase (V-ATPase), a multisubunit enzyme that mediates acidification of eukaryotic intracellular organelles. V-ATPase dependent organelle acidification is necessary for such intracellular processes as protein sorting, zymogen activation, receptor-mediated endocytosis, and synaptic vesicle proton gradient generation. V-ATPase is composed of a cytosolic V1 domain and a transmembrane V0 domain. The V1 domain consists of three A and three B subunits, two G subunits plus the C, D, E, F, and H subunits. The V1 domain contains the ATP catalytic site. The V0 domain consists of five different subunits: a, c, c', c", and d. Additional isoforms of many of the V1 and V0 subunit proteins are encoded by multiple genes or alternatively spliced transcript variants. This encoded protein is one of two V1 domain A subunit isoforms and is found in all tissues. Transcript variants derived from alternative polyadenylation exist. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the ATP6V1A gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 17 curated pathogenic missense variants (we use a threshold of 10). The gene has 5 curated benign missense variants. Gene score misZ: 3.3731 (above the threshold of 3.09). Trascript score misZ: 4.7152 (above the threshold of 3.09). GenCC associations: The gene is linked to autosomal recessive cutis laxa type 2, classic type, undetermined early-onset epileptic encephalopathy, epileptic encephalopathy, infantile or early childhood, 3, autosomal recessive cutis laxa type 2D.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.82
