Genes affected

SLC9A1 (HGNC:11071): (solute carrier family 9 member A1) This gene encodes a Na+/H+ antiporter that is a member of the solute carrier family 9. The encoded protein is a plasma membrane transporter that is expressed in the kidney and intestine. This protein plays a central role in regulating pH homeostasis, cell migration and cell volume. This protein may also be involved in tumor growth. [provided by RefSeq, Sep 2011]

This variant is present in population databases (rs750040030, gnomAD 0.04%). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with SLC9A1-related conditions. This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 765 of the SLC9A1 protein (p.Arg765Trp). -
