Genes affected
MYL4 (HGNC:7585): (myosin light chain 4) Myosin is a hexameric ATPase cellular motor protein. It is composed of two myosin heavy chains, two nonphosphorylatable myosin alkali light chains, and two phosphorylatable myosin regulatory light chains. This gene encodes a myosin alkali light chain that is found in embryonic muscle and adult atria. Two alternatively spliced transcript variants encoding the same protein have been found for this gene.

Atrial fibrillation, familial, 18 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeNov 15, 2023This variant, c.60_65del, results in the deletion of 2 amino acid(s) of the MYL4 protein (p.Ala30_Pro31del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs766730973, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with MYL4-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
