Similarly, since myofibre-specific depletion of Fukutin (Fktn) in mice results in a mild myopathy compared to the more severe muscle wasting reported when the Fktn gene is specifically depleted in satellite cells, it is plausible that satellite cell dysfunction contributes to MDDGA4 (Fukuyama/FKTN related dystrophy (OMIM: 253800) [188,189]. The gene discussed is FKTN; the disease is myopathy.
