Genes affected
SLC9A2 (HGNC:11072): (solute carrier family 9 member A2) This gene encodes a member of the sodium-hydrogen exchanger (NHE) protein family. These proteins are involved in sodium-ion transport by exchanging intracellular hydrogen ions to external sodium ions and help in the regulation of cell pH and volume. The encoded protein is localized to the apical membrane and is involved in apical absorption of sodium. [provided by RefSeq, Jun 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2023The c.82C>T (p.P28S) alteration is located in exon 1 (coding exon 1) of the SLC9A2 gene. This alteration results from a C to T substitution at nucleotide position 82, causing the proline (P) at amino acid position 28 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
