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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2022The c.85C>G (p.P29A) alteration is located in exon 1 (coding exon 1) of the SSTR4 gene. This alteration results from a C to G substitution at nucleotide position 85, causing the proline (P) at amino acid position 29 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
