CHKB deficiency disrupts mitochondrial function and is linked to muscular dystrophy, while PC supplementation restores membrane integrity in neurodegenerative contexts (Aoyama et al. 2004; van der Veen et al. 2017; Tavasoli et al. 2022; Mejia and Hatch 2016). The gene discussed is CHKB; the disease is muscular dystrophy.
