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 GeneticsJul 26, 2022The c.424A>G (p.M142V) alteration is located in exon 6 (coding exon 6) of the CRCP gene. This alteration results from a A to G substitution at nucleotide position 424, causing the methionine (M) at amino acid position 142 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
