Genes affected

MYL5 (HGNC:7586): (myosin light chain 5) This gene encodes one of the myosin light chains, a component of the hexameric ATPase cellular motor protein myosin. Myosin is composed of two heavy chains, two nonphosphorylatable alkali light chains, and two phosphorylatable regulatory light chains. This gene product, one of the regulatory light chains, is expressed in fetal muscle and in adult retina, cerebellum, and basal ganglia. [provided by RefSeq, Jul 2008]

Ambry Genetics

Aug 12, 2021

The c.323C>T (p.A108V) alteration is located in exon 5 (coding exon 5) of the MYL5 gene. This alteration results from a C to T substitution at nucleotide position 323, causing the alanine (A) at amino acid position 108 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
