Peroxisomal fatty acyl-CoA reductase 1 (FAR1) disorder is a peroxisomal disorder, that is also referred to as rhizomelic chondrodysplasia punctata type 4 (RCDP4). It is characterized by syndromic severe intellectual disability with cataracts, epilepsy, and growth retardation but without rhizomelia or skeletal abnormalities. Mutations in FAR1, producing fatty alcohols used in plasmalogen biosynthesis, were recently shown to cause this disease.
