[NP-detecting DNA technologies: solving problems of applied biochemistry]

Area of Science:

• Genetics
• Sports Science
• Molecular Biology

Background:

• Genetic factors significantly influence athletic performance.
• Understanding gene variations like those in ACTN3 and GHR can provide insights into muscle function and performance.
• The role of the CANP3 gene in athletic populations requires further investigation.

Purpose of the Study:

• To investigate heterozygosity of the CANP3, ACTN3, and GHR genes in specialized athlete collections.
• To identify novel genetic variations and analyze their association with high muscular performance.
• To utilize advanced DNA analysis technologies for comprehensive genetic profiling.

Main Methods:

• Employed state-of-the-art DNA technologies for genetic analysis.
• Identified gene variations including a novel dinucleotide deletion (AC) in the CANP3 gene.
• Utilized real-time PCR assays to analyze single nucleotide polymorphisms (SNPs) in ACTN3 and GHR genes.

Main Results:

• A novel dinucleotide deletion (AC) was identified in the CANP3 gene in five heterozygous individuals.
• The ACTN3 gene polymorphism (SNP1747 C-->T) showed a positive association between allele C and high muscular performance.
• The GHR gene polymorphism (SNP1630 A-->C) suggested a potential negative association between allele C and high muscular performance.

Conclusions:

• Specific genetic variations in CANP3, ACTN3, and GHR genes are associated with athletic performance.
• The identified CANP3 deletion represents a novel genetic finding in athletes.
• These findings contribute to understanding the genetic basis of elite athletic capabilities.
