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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2024The c.495G>C (p.E165D) alteration is located in exon 5 (coding exon 5) of the MYL1 gene. This alteration results from a G to C substitution at nucleotide position 495, causing the glutamic acid (E) at amino acid position 165 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
