We focused this analysis on four genes that are closely linked to muscle atrophy (MSTN) (Jones et al. 2004) and fast‐twitch, glycolytic muscle properties (ANKRD1, MYH8 and MYCBP2) (Qin et al. 1994; Nakamura et al. 2002; Stevenson et al. 2006). The gene discussed is MYCBP2; the disease is muscle atrophy.
