Association between the ACTN3 R577X polymorphism and artistic gymnastic performance in Italy.

Genetic testing and molecular biomarkers - 1 Jun 2009

Massidda Myosotis, Vona Giuseppe, Calò Carla M

Abstract excerpt

The ACTN3 (R577X) gene encodes for a structural protein that is exclusively expressed in the Z-disc of type II muscle fibers. Homozygosis (577XX) for the stop codon in the ACTN3 polymorphism results in alpha-actinin-3 complete deficiency. Previous studies have shown low frequencies of the ACTN3 XX genotype in elite sprinters compared to the general population. This study tests 35 Italian elite gymnasts and 53...
