Genes affected

ASIC5 (HGNC:17537): (acid sensing ion channel subunit family member 5) This gene belongs to the amiloride-sensitive Na+ channel and degenerin (NaC/DEG) family, members of which have been identified in many animal species ranging from the nematode to human. The amiloride-sensitive Na(+) channel encoded by this gene is primarily expressed in the small intestine, however, its exact function is not known. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.803

The c.1201T>C (p.S401P) alteration is located in exon 8 (coding exon 8) of the ASIC5 gene. This alteration results from a T to C substitution at nucleotide position 1201, causing the serine (S) at amino acid position 401 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
