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]

The c.2371A>G (p.I791V) alteration is located in exon 12 (coding exon 12) of the SLC9A1 gene. This alteration results from a A to G substitution at nucleotide position 2371, causing the isoleucine (I) at amino acid position 791 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with SLC9A1-related conditions. This variant is present in population databases (rs140754742, gnomAD 0.01%). This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 791 of the SLC9A1 protein (p.Ile791Val). -
