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]

LOC105377507 links:

TDO2 (HGNC:11708): (tryptophan 2,3-dioxygenase) This gene encodes a heme enzyme that plays a critical role in tryptophan metabolism by catalyzing the first and rate-limiting step of the kynurenine pathway. Increased activity of the encoded protein and subsequent kynurenine production may also play a role in cancer through the suppression of antitumor immune responses, and single nucleotide polymorphisms in this gene may be associated with autism.

Ambry Genetics

Jan 03, 2024

The c.92C>T (p.P31L) alteration is located in exon 2 (coding exon 2) of the ASIC5 gene. This alteration results from a C to T substitution at nucleotide position 92, causing the proline (P) at amino acid position 31 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
