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]

MYL5 links:

SLC49A3 (HGNC:26177): (solute carrier family 49 member 3) Predicted to enable transmembrane transporter activity. Predicted to be involved in transmembrane transport. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.457G>C (p.A153P) alteration is located in exon 7 (coding exon 7) of the MYL5 gene. This alteration results from a G to C substitution at nucleotide position 457, causing the alanine (A) at amino acid position 153 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
