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]

The c.342C>A (p.F114L) alteration is located in exon 1 (coding exon 1) of the SSTR4 gene. This alteration results from a C to A substitution at nucleotide position 342, causing the phenylalanine (F) at amino acid position 114 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
