Abstract
The proband presented with bilateral congenital non-progressive ptosis and limitation of eye rotation since childhood. The diagnosis was congenital fibrosis of the extraocular muscles. A new KIF21 pathogenic mutation locus was found. It was a KIF21A-ex20 c.2821C>T (p.Arg941Trp) heterozygous missense mutation, which caused the disease in this family.
