Kudo et al. (19) observed that anti-muscular dystrophy gene peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α) as well as pro-inflammatory cytokines TNF‐α and IL-6 were significantly increased in multifidus from patients with lumbar kyphosis (a reduced lumbar lordosis) compared with normal lumbar lordosis. The gene discussed is PPARGC1A; the disease is muscular dystrophy.
