Apart from the general notion that DYN2 mutations give rise to severe neuromuscular disorders (González-Jamett et al., 2013), it was recently observed that Schwann cells ablated for DYN2 display cell cycle progression and cytokinesis defects associated with severe demyelination and peripheral neuropathy development (Gerber et al., 2019). The gene discussed is DNM2; the disease is peripheral neuropathy.
