Genes affected

SSTR2 (HGNC:11331): (somatostatin receptor 2) Somatostatin acts at many sites to inhibit the release of many hormones and other secretory proteins. The biologic effects of somatostatin are probably mediated by a family of G protein-coupled receptors that are expressed in a tissue-specific manner. SSTR2 is a member of the superfamily of receptors having seven transmembrane segments and is expressed in highest levels in cerebrum and kidney. [provided by RefSeq, Jul 2008]

The c.49A>G (p.I17V) alteration is located in exon 2 (coding exon 1) of the SSTR2 gene. This alteration results from a A to G substitution at nucleotide position 49, causing the isoleucine (I) at amino acid position 17 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
