Furthermore, mutations in ELOVL4, a key enzyme in the synthesis of VLC‐PUFAs, have been identified in Stargardt‐like macular dystrophy (STGD3), a juvenile retinal dystrophy with macular deposits reminiscent of AMD (Bernstein, 2001; Edwards, Donoso, & Ritter, 2001; Zhang, 2001). The gene discussed is ELOVL4; the disease is age-related macular degeneration.
