The sco paralysis phenotype could be tied to loss of gas1a, a factor involved in skeletal myogenesis (Leem et al. 2011), and/or smn1, which is associated with skeletal muscle atrophy, caused by progressive loss of motor neurons (Fallini et al. 2012; Hao Le et al. 2017). This evidence concerns the gene SMN1 and Skeletal muscle atrophy.
