Genes affected

MYL1 (HGNC:7582): (myosin light chain 1) Myosin is a hexameric ATPase cellular motor protein. It is composed of two heavy chains, two nonphosphorylatable alkali light chains, and two phosphorylatable regulatory light chains. This gene encodes a myosin alkali light chain expressed in fast skeletal muscle. Two transcript variants have been identified for this gene. [provided by RefSeq, Jul 2008]

The c.553G>A (p.E185K) alteration is located in exon 5 (coding exon 5) of the MYL1 gene. This alteration results from a G to A substitution at nucleotide position 553, causing the glutamic acid (E) at amino acid position 185 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
