Genes affected

ATP6V0A1 (HGNC:865): (ATPase H+ transporting V0 subunit a1) 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 gene encodes one of three A subunit proteins and the encoded protein is associated with clathrin-coated vesicles. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PP2

Missense variant where missense usually causes diseases, ATP6V0A1

BP4

Computational evidence support a benign effect (MetaRNN=0.21465352).

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.00024 (350/1461014) while in subpopulation NFE AF= 0.000297 (330/1111612). AF 95% confidence interval is 0.00027. There are 0 homozygotes in gnomad4_exome. There are 158 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.1307G>A (p.R436Q) alteration is located in exon 12 (coding exon 11) of the ATP6V0A1 gene. This alteration results from a G to A substitution at nucleotide position 1307, causing the arginine (R) at amino acid position 436 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
