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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2023The c.853G>A (p.V285M) alteration is located in exon 10 (coding exon 10) of the SLC9A8 gene. This alteration results from a G to A substitution at nucleotide position 853, causing the valine (V) at amino acid position 285 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
