Genes affected

ACTN3 (HGNC:165): (actinin alpha 3) This gene encodes a member of the alpha-actin binding protein gene family. The encoded protein is primarily expressed in skeletal muscle and functions as a structural component of sarcomeric Z line. This protein is involved in crosslinking actin containing thin filaments. An allelic polymorphism in this gene results in both coding and non-coding variants; the reference genome represents the coding allele. The non-functional allele of this gene is associated with elite athlete status. [provided by RefSeq, Feb 2014]

Ambry Genetics

Oct 26, 2022

The c.445G>A (p.A149T) alteration is located in exon 4 (coding exon 4) of the ACTN3 gene. This alteration results from a G to A substitution at nucleotide position 445, causing the alanine (A) at amino acid position 149 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
