To date, nine different mutations in the human ELOVL4 gene have been identified that cause neurological disorders (Bernstein et al., 2001; Edwards et al., 2001; Zhang et al., 2001; Aldahmesh et al., 2011; Cadieux-Dion et al., 2014; Mir et al., 2014; Bourassa et al., 2015; Ozaki et al., 2015; Agbaga, 2016). Here, ELOVL4 is linked to nervous system disorder.
