General SNP Description

C/C genotype indicates better performing muscles, particularly for sprinting and power sports. Professional sprinters usually have this, although it is less common for endurance athletes. The C/T genotype is normal for Caucasian people. This genotype may indicate somewhat impaired muscles, however many sprinters and some endurance athletes have this. The T/T genotype is underrepresented in elite strength and sprint athletes, consistent with previous reports of impaired muscle performance. However, this is more common in endurance athletes. In females, the R allele of this SNP is associated with sprinters, while the X allele is associated with endurance athletes.This gene is primarily expressed in the skeletal muscle and is associated with human elite athletic performance. Diseases associated with this gene include Muscular Dystrophies.
