Genes affected

MYL2 (HGNC:7583): (myosin light chain 2) This gene encodes a major sarcomeric protein in mammalian striated muscle. The encoded protein plays a role in embryonic heart muscle structure and function, while phosphorylation of the encoded protein is involved in cardiac myosin cycling kinetics, torsion and function in adults. Mutations in this gene are associated with hypertrophic cardiomyopathy 10 and infant-onset myopathy. [provided by RefSeq, May 2022]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: MYL2 c.*10C>T is located in the untranslated mRNA region downstream of the termination codon. The variant allele was found at a frequency of 0.00016 in 250532 control chromosomes. The observed variant frequency is approximately 2.13 fold of the estimated maximal expected allele frequency for a pathogenic variant in MYL2 causing Hypertrophic Cardiomyopathy phenotype (7.5e-05), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.*10C>T in individuals affected with Hypertrophic Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. One laboratory classified the variant as benign/likely benign, and one laboratory classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as benign. -
