Genes affected

NHERF2 (HGNC:11076): (NHERF family PDZ scaffold protein 2) This gene encodes a member of the NHERF family of PDZ scaffolding proteins. These proteins mediate many cellular processes by binding to and regulating the membrane expression and protein-protein interactions of membrane receptors and transport proteins. The encoded protein plays a role in intestinal sodium absorption by regulating the activity of the sodium/hydrogen exchanger 3, and may also regulate the cystic fibrosis transmembrane regulator (CFTR) ion channel. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

The c.512G>C (p.R171P) alteration is located in exon 3 (coding exon 3) of the SLC9A3R2 gene. This alteration results from a G to C substitution at nucleotide position 512, causing the arginine (R) at amino acid position 171 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
