A mutation in exon 9a (p.Asp365Gly) of FAR1, a gene of the plasmalogen–biosynthesis pathway, causes rhizomelic chondrodysplasia punctata (RCDP), a disease that is characterized by severe intellectual disability with cataracts, epilepsy and growth retardation (Buchert et al, 2014). Here, FAR1 is linked to epilepsy.
