The study conducted by Shrestha et al. in 2024 explored the association between BDKRB2 polymorphisms and physical performance and muscle mass in older adults with sarcopenia and found that in men, the rs1799722 TT genotype was associated with longer 6MWDs and a greater leg muscle mass, while the rs5810761 -9-9 genotype was associated with a lower arm fat mass [29]. This evidence concerns the gene BDKRB2 and sarcopenia.
