Genes affected

ACTN2 (HGNC:164): (actinin alpha 2) Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha actinin is an actin-binding protein with multiple roles in different cell types. In nonmuscle cells, the cytoskeletal isoform is found along microfilament bundles and adherens-type junctions, where it is involved in binding actin to the membrane. In contrast, skeletal, cardiac, and smooth muscle isoforms are localized to the Z-disc and analogous dense bodies, where they help anchor the myofibrillar actin filaments. This gene encodes a muscle-specific, alpha actinin isoform that is expressed in both skeletal and cardiac muscles. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2013]

Variant summary: Variant Summary: The c.441G.A (p.Ser147=) in ACTN2 gene is a synonymous change that involves a non-conserved nucleotide with a prediction of being a "disease-causing" by mutation taster. 4/5 programs in Alamut predict that this variant does not affect normal splicing, however no functional studies supporting this notion were published at the time of evaluation. The variant is present in the control population dataset of ExAC at an overall allele frequency of 0.036% (44/121320 chrs tested), mainly in individuals of African descent (0.32%; 33/10388 chrs tested). The observed frequency exceeds the maximum expected allele frequency for a pathogenic ACTN2 variant (0.0025%), suggesting that it is a common polymorphism. The variant of interest has not, to our knowledge, been reported in affected individuals via published reports. Variant was identified in one individual undergoing genetic screening for CMYO panel, who tested positive for a known pathogenic variant in TTR. Lastly, the variant has been reported as Benign by a reputable database/clinical laboratory. Taken together, the variant was classified as Benign. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
