Jun 20, 2022 · What does the ACTN3 gene do? The ACTN3 gene encodes the alpha actinin 3 protein found in fast-twitch muscles. Fast-twitch muscles are responsible for explosive bursts of power or speed. A common genetic variant in the ACTN3 gene causes about 20% of the population not to produce fast-twitch skeletal muscle fibers.

ACTN3 is a gene that encodes for alpha-actinin-3, a protein expressed only in type-II muscle fibers (North et al., 1999). A common polymorphism in this gene is R577X (rs1815739), where a C-to-T base substitution results in the transformation of an arginine base (R) to a …

Nov 30, 2008 · The ATLAS test looks at a common genetic variation within the ACTN3 gene, which has been associated in numerous studies with elite athlete status and with variation in muscle strength and...

Oct 5, 2023 · The ACTN3 gene encodes a protein and is found in fast-twitch muscle fibers. It is associated with sudden explosive muscle power and is said to influence athletic performance. The ACTN3 gene has three variations: R/R, R/X and X/X.

Dec 20, 2023 · Actn3 gene testing has gained popularity in recent years as a means to assess an individual’s genetic predisposition for athletic performance. By analyzing an individual’s ACTN3 gene variants, it is possible to determine whether they have the potential to excel in power-based sports or activities.

There is a genetic test known as ACTN3-genotyping-Sports-Gene test which is done on the athletes to find out the roles played by the sports gene. It is worth to note that ACTN3 produces alpha-actinin-3 that is found in fast twitch muscle fibers.

Several investigations have found that α-actinin-3 deficiency due to XX homozygosity in the ACTN3 R577X polymorphism can negatively affect sports performance through several structural, metabolic, or signaling changes.

The ACTN3 gene controls which type of fibres is more frequent in your skeletal muscles. What are we testing? This project explores the genetic variation of the gene ACTN3 r577x.

The ACTN3 test is a genetic screening tool that delves into the genetic code to identify variations in the ACTN3 gene, known as polymorphisms. These genetic variations can influence the production of alpha-actinin-3 and, consequently, the performance of fast-twitch muscle fibers.

Discover the comprehensive Actn3 gene test, offering insights into Actn3 genotyping, R577X gene analysis, and genetic screening for ACTN3 protein deficiency, aiding in the assessment of sprint gene mutations and fast-twitch muscle fiber potential.
