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]

Ambry Genetics

Dec 18, 2023

The c.211A>T (p.T71S) alteration is located in exon 3 (coding exon 3) of the MYL1 gene. This alteration results from a A to T substitution at nucleotide position 211, causing the threonine (T) at amino acid position 71 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
