Genes affected
SCTR (HGNC:10608): (secretin receptor) The protein encoded by this gene is a G protein-coupled receptor and belongs to the glucagon-VIP-secretin receptor family. It binds secretin which is the most potent regulator of pancreatic bicarbonate, electrolyte and volume secretion. Secretin and its receptor are suggested to be involved in pancreatic cancer and autism. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 06, 2023The c.971T>G (p.L324R) alteration is located in exon 10 (coding exon 10) of the SCTR gene. This alteration results from a T to G substitution at nucleotide position 971, causing the leucine (L) at amino acid position 324 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
