ELOVL5 and cerebellar ataxia: Neuronal ELOVL4 and astrocytic ELOVL5, where inactivating mutations are known to result in ataxia variants named SCA34 and SCA38 [77,130,131], were investigated further regarding protein abundance and exhibited significantly diminished levels for ELOVL4 (46%, p = 0.0002), while the antibody for ELOVL5 did not generate specific bands (Figure 6B).
