Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the ATP6V1B1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Non-catalytic subunit of the peripheral V1 complex of vacuolar ATPase. V-ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells.
• Disease: DISEASE: Renal tubular acidosis, distal, with progressive nerve deafness (dRTA-D) [MIM:267300]: An autosomal recessive disease characterized by the association of renal distal tubular acidosis with sensorineural hearing loss. Distal renal tubular acidosis is characterized by reduced ability to acidify urine, variable hyperchloremic hypokalemic metabolic acidosis, nephrocalcinosis, and nephrolithiasis. It is due to functional failure of alpha- intercalated cells of the cortical collecting duct of the distal nephron, where vectorial proton transport is required for urinary acidification. {ECO:0000269|PubMed:12414817, ECO:0000269|PubMed:12579397, ECO:0000269|PubMed:9916796}. Note=The disease is caused by mutations affecting the gene represented in this entry.
