Association of polymorphisms rs2303729, rs10880, and rs1131620 of with sarcopenia in elderly patients with type 2 diabetes mellitus.

Background: Latent TGFβ binding protein 4 () modifies skeletal muscle function, and polymorphisms in this gene have been associated with a longer ambulation time in patients with Duchenne muscular dystrophy. However, no studies associate these polymorphisms with an acquired muscle condition.

Aim: The study aims to determine whether three functional variants within the were associated with sarcopenia in patients with type 2 diabetes mellitus (T2DM).
