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]

The c.288A>T (p.K96N) alteration is located in exon 3 (coding exon 3) of the ACTN3 gene. This alteration results from a A to T substitution at nucleotide position 288, causing the lysine (K) at amino acid position 96 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
