The Effect of Heterozygosity for the ACTN3 Null Allele on Human Muscle Performance
HETEROZYGOUS QUANTITATIVE TRAIT LOCI
2017/4/13
α-Actinin-3 is primarily expressed in fast (Type II) fibers in the human skeletal muscle. Over 70% of the global population has at least one copy of a loss of function allele because of a premature st...
