Genes affected

TMEM213 (HGNC:27220): (transmembrane protein 213) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

TMEM213 links:

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]

The c.68C>T (p.S23L) alteration is located in exon 1 (coding exon 1) of the TMEM213 gene. This alteration results from a C to T substitution at nucleotide position 68, causing the serine (S) at amino acid position 23 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
