Genes affected

ASIC3 (HGNC:101): (acid sensing ion channel subunit 3) This gene encodes a member of the degenerin/epithelial sodium channel (DEG/ENaC) superfamily. The members of this family are amiloride-sensitive sodium channels that contain intracellular N and C termini, two hydrophobic transmembrane regions, and a large extracellular loop, which has many cysteine residues with conserved spacing. The member encoded by this gene is an acid sensor and may play an important role in the detection of lasting pH changes. In addition, a heteromeric association between this member and acid-sensing (proton-gated) ion channel 2 has been observed as proton-gated channels sensitive to gadolinium. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2012]

Collection Method: clinical testing

The c.328G>T (p.A110S) alteration is located in exon 1 (coding exon 1) of the ASIC3 gene. This alteration results from a G to T substitution at nucleotide position 328, causing the alanine (A) at amino acid position 110 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
