Genes affected

SSTR4 (HGNC:11333): (somatostatin receptor 4) 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. SSTR4 is a member of the superfamily of receptors having seven transmembrane segments and is expressed in highest levels in fetal and adult brain and lung. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jul 09, 2021

The c.719C>T (p.A240V) alteration is located in exon 1 (coding exon 1) of the SSTR4 gene. This alteration results from a C to T substitution at nucleotide position 719, causing the alanine (A) at amino acid position 240 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
