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]

Likely pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Jun 10, 2023 | In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 26208211, 27247958, 35368817, 31738409) - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 21, 2023 | This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 411 of the ATP6V0A4 protein (p.Asp411Tyr). This variant is present in population databases (rs763982675, gnomAD 0.04%). This missense change has been observed in individual(s) with renal tubular acidosis (PMID: 26208211, 27247958). 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: 384333). 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%. For these reasons, this variant has been classified as Pathogenic. - |

Autosomal recessive distal renal tubular acidosis Pathogenic:2
Likely pathogenic, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Oct 26, 2018 | The ATP6V0A4 c.1231G>T (p.Asp411Tyr) variant has been described in two studies in which it was found in a total of six patiens with distal renal tubular acidosis from five families, including four in a homozygous state and two in a compound heterozygous state (Pereira et al. 2015; Escobar et al. 2016). The Asp411 residue is highly conserved. Control data are unavailable for this variant, which is reported at a frequency of 0.00061 in the Latino population of the Exome Aggregation Consortium. Based on the evidence, the p.Asp411Tyr variant is classified as likely pathogenic for recessive distal renal tubular acidosis. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. - |
Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jun 02, 2022 | Variant summary: ATP6V0A4 c.1231G>T (p.Asp411Tyr) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-05 in 251452 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in ATP6V0A4 causing Renal Tubular Acidosis, Distal, Autosomal Recessive (8e-05 vs 0.0011), allowing no conclusion about variant significance. c.1231G>T has been reported in the literature in multiple individuals affected with Renal Tubular Acidosis, Distal, Autosomal Recessive (example, Escobar_2016, Pereira_2015, Mansilla_2021). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |
ATP6V0A4-related disorder Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Apr 20, 2023 | The ATP6V0A4 c.1231G>T variant is predicted to result in the amino acid substitution p.Asp411Tyr. This variant has been reported to be pathogenic for distal renal tubular acidosis (dRTA) (Escobar et al. 2016. PubMed ID: 27247958; reported as c.1232G>T in Pereira et al. 2015. PubMed ID: 26208211). Escobar et al. suggested this is a founder variant in individuals of Mexican ancestry. This variant is reported in 0.043% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-138432259-C-A). This variant is interpreted as pathogenic. - |
