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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.89C>A (p.T30N) alteration is located in exon 2 (coding exon 1) of the SSTR2 gene. This alteration results from a C to A substitution at nucleotide position 89, causing the threonine (T) at amino acid position 30 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
