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 GeneticsMar 16, 2024The c.61C>T (p.L21F) alteration is located in exon 2 (coding exon 1) of the SSTR2 gene. This alteration results from a C to T substitution at nucleotide position 61, causing the leucine (L) at amino acid position 21 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
