Genes affected

CALCA (HGNC:1437): (calcitonin related polypeptide alpha) This gene encodes the peptide hormones calcitonin, calcitonin gene-related peptide and katacalcin by tissue-specific alternative RNA splicing of the gene transcripts and cleavage of inactive precursor proteins. Calcitonin is involved in calcium regulation and acts to regulate phosphorus metabolism. Calcitonin gene-related peptide functions as a vasodilator and as an antimicrobial peptide while katacalcin is a calcium-lowering peptide. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2014]

CALCA links:

CALCB (HGNC:1438): (calcitonin related polypeptide beta) Predicted to enable calcitonin receptor binding activity. Predicted to be involved in adenylate cyclase-activating G protein-coupled receptor signaling pathway and regulation of cytosolic calcium ion concentration. Predicted to be located in extracellular region. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Dec 07, 2024

The c.50T>C (p.L17P) alteration is located in exon 2 (coding exon 1) of the CALCA gene. This alteration results from a T to C substitution at nucleotide position 50, causing the leucine (L) at amino acid position 17 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
