Genes affected

SLC9A8 (HGNC:20728): (solute carrier family 9 member A8) Sodium-hydrogen exchangers (NHEs), such as SLC9A8, are integral transmembrane proteins that exchange extracellular Na+ for intracellular H+. NHEs have multiple functions, including intracellular pH homeostasis, cell volume regulation, and electroneutral NaCl absorption in epithelia (Xu et al., 2008 [PubMed 18209477]).[supplied by OMIM, Apr 2009]

Ambry Genetics

Feb 12, 2024

The c.113C>T (p.P38L) alteration is located in exon 2 (coding exon 2) of the SLC9A8 gene. This alteration results from a C to T substitution at nucleotide position 113, causing the proline (P) at amino acid position 38 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
