Genes affected
SLC9A4 (HGNC:11077): (solute carrier family 9 member A4) Predicted to enable potassium:proton antiporter activity and sodium:proton antiporter activity. Predicted to be involved in potassium ion transmembrane transport; regulation of intracellular pH; and sodium ion import across plasma membrane. Predicted to act upstream of or within epithelial cell development and gastric acid secretion. Predicted to be located in several cellular components, including apical plasma membrane; basolateral plasma membrane; and vacuolar membrane. Predicted to be integral component of membrane. Predicted to be active in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 03, 2024The c.571G>A (p.V191I) alteration is located in exon 2 (coding exon 2) of the SLC9A4 gene. This alteration results from a G to A substitution at nucleotide position 571, causing the valine (V) at amino acid position 191 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
