Genes affected
CRCP (HGNC:17888): (CGRP receptor component) This gene encodes a membrane protein that functions as part of a receptor complex for a small neuropeptide that increases intracellular cAMP levels. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.269G>A (p.R90Q) alteration is located in exon 5 (coding exon 5) of the CRCP gene. This alteration results from a G to A substitution at nucleotide position 269, causing the arginine (R) at amino acid position 90 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
