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]

The c.403A>C (p.N135H) alteration is located in exon 6 (coding exon 6) of the CRCP gene. This alteration results from a A to C substitution at nucleotide position 403, causing the asparagine (N) at amino acid position 135 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
