Genes affected

SLC9A7 (HGNC:17123): (solute carrier family 9 member A7) This gene encodes a sodium and potassium/ proton antiporter that is a member of the solute carrier family 9 protein family. The encoded protein is primarily localized to the trans-Golgi network and is involved in maintaining pH homeostasis in organelles along the secretory and endocytic pathways. This protein may enhance cell growth of certain breast tumors. This gene is part of a gene cluster on chromosome Xp11.23. A pseudogene of this gene is found on chromosome 12. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Mar 2012]

The c.2132C>G (p.S711W) alteration is located in exon 17 (coding exon 17) of the SLC9A7 gene. This alteration results from a C to G substitution at nucleotide position 2132, causing the serine (S) at amino acid position 711 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
