A new locus for autosomal dominant congenital coronary cataract in a Chinese family maps to chromosome 3q.

Purpose: To identify the genetic defect in an autosomal dominant congenital coronary cataract family (ADCCC).

Methods: A Chinese family with ADCC was identified and characterized. All the members were genotyped with microsatellite markers at genes and loci that were considered to be associated with hereditary cataracts.
