A novel fan-shaped cataract-microcornea syndrome caused by a mutation of CRYAA in an Indian family.

Abstract

This study provides the report of mapping a locus for syndromal cataract (cataract-microcornea syndrome) on 21q22.3. The mutation observed in CRYAA in the present family highlights the phenotypic heterogeneity of the disorder in relation to the genotype, as an identical mutation has previously been reported in an American family with a different type of cataract. The "fan-shaped cataract" observed in the present family has not been reported before.
