A very rare congenital limb malformation syndrome characterized by absence deformity of one leg, progressive scoliosis, short stature, and congenital cataract associated with dysplasia of the optic nerve. No intellectual deficit has been reported. There have been no further descriptions in the literature since 1968.

Mutations in the CRYAA gene have been found to cause multiple types of cataract, which have been described as nuclear, zonular central nuclear, laminar, lamellar, anterior polar, posterior polar, cortical, embryonal, anterior subcapsular, fan-shaped, and total. Cataract associated with microcornea, sometimes called the cataract-microcornea syndrome, is also caused by mutation in the CRYAA gene. Both autosomal dominant and autosomal recessive modes of inheritance have been reported. The symbol CATC1 was formerly used for the autosomal recessive form of cataract caused by mutation in the CRYAA gene.

Rare syndrome with manifestation of progressive sensorineural hearing loss due to severe cochleosaccular degeneration and cataract. So far reported in two families. Transmission is autosomal dominant.

Mutations in the BFSP2 gene have been found to cause multiple types of cataract, which have been described as juvenile-onset lamellar, cortical, nuclear embryonic; and congenital nuclear, sutural, stellate, Y-sutural, and punctate cortical.
