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.2272G>A (p.D758N) alteration is located in exon 12 (coding exon 12) of the SLC9A1 gene. This alteration results from a G to A substitution at nucleotide position 2272, causing the aspartic acid (D) at amino acid position 758 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
