Genes affected

CALD1 (HGNC:1441): (caldesmon 1) This gene encodes a calmodulin- and actin-binding protein that plays an essential role in the regulation of smooth muscle and nonmuscle contraction. The conserved domain of this protein possesses the binding activities to Ca(2+)-calmodulin, actin, tropomyosin, myosin, and phospholipids. This protein is a potent inhibitor of the actin-tropomyosin activated myosin MgATPase, and serves as a mediating factor for Ca(2+)-dependent inhibition of smooth muscle contraction. Alternative splicing of this gene results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.448G>A (p.E150K) alteration is located in exon 5 (coding exon 3) of the CALD1 gene. This alteration results from a G to A substitution at nucleotide position 448, causing the glutamic acid (E) at amino acid position 150 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
