Genes affected

ATP6V0A4 (HGNC:866): (ATPase H+ transporting V0 subunit a4) This gene encodes a component of vacuolar ATPase (V-ATPase), a multisubunit enzyme that mediates acidification of intracellular compartments of eukaryotic cells. V-ATPase dependent 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. This gene is one of four genes in man and mouse that encode different isoforms of the a subunit. Alternatively spliced transcript variants encoding the same protein have been described. Mutations in this gene are associated with renal tubular acidosis associated with preserved hearing. [provided by RefSeq, Jul 2008]

Pathogenic:3

Pathogenic, no assertion criteria provided	literature only	OMIM	Nov 01, 2002	- -
Likely pathogenic, criteria provided, single submitter	clinical testing	Neuberg Centre For Genomic Medicine, NCGM	-	The ATP6V0A4 c.2420G>A (p.Arg807Gln) variant has been reported in heterozygous state in individuals affected with distal renal tubular acidosis 3, with or without sensorineural hearing loss (Stover EH et. al., 2002). The amino acid Arg at position 807 is changed to a Gln changing protein sequence and it might alter its composition and physico-chemical properties. This variant has been reported to the ClinVar database as Pathogenic/Likely pathogenic. It has allele frequency of 0.004% in gnomAD database. The variant is predicted to be damaging by both SIFT and PolyPhen2. The amino acid change p.Arg807Gln in ATP6V0A4 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Likely Pathogenic. -

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jan 25, 2024	This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 807 of the ATP6V0A4 protein (p.Arg807Gln). This variant is present in population databases (rs28939081, gnomAD 0.02%). This missense change has been observed in individual(s) with renal tubular acidosis (PMID: 12414817, 23754897, 29202719). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 5159). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ATP6V0A4 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects ATP6V0A4 function (PMID: 18632794). For these reasons, this variant has been classified as Pathogenic. -
