The Claim
In Chinese Han men undergoing resistance training, the rs1544410-CC genotype is associated with greater increases in quadriceps muscle thickness compared to individuals carrying the CT genotype, indicating a sex-specific genetic influence on muscle hypertrophy.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In Chinese men who lift weights, those with a specific gene version (CC) tend to get bigger quadriceps muscles than those with a different version (CT), and this gene effect might only happen in men.

In Chinese Han men undergoing resistance training, the rs1544410-CC genotype is associated with greater increases in quadriceps muscle thickness compared to CT carriers, suggesting a sex-specific genetic influence on muscle hypertrophy.
What the research says
1 studyStudy: VDR Gene Polymorphisms and Inter-Individual Variability in Response to Resistance Training.
The study found that Chinese Han men with a specific gene version (CC) got bigger thigh muscles from weight training than those with another version (CT), which is exactly what the claim says.
