Purpose: To identify the CRYBA1/A3 mutation spectrum and analyze the genotype-phenotype correlations in Chinese families with congenital cataract. Methods: Family history and clinical data of 47 unrelated families with autosomal dominant congenital cataract (ADCC) were recorded. CRYBA1/A3 gene sequencing was applied to identify the causative mutation. Haplotypes were constructed using closely linked microsatellite markers and intragenic single-nucleotide polymorphisms (SNPs) to compare the affected haplotype in three families. Results: Nuclear cataract was the most common type of ADCC in Chinese families, accounting for 42.6% (20/47). A recurrent CRYBA1/A3 deletion mutation (Delta G91) was identified in three families (6.4%) with nonprogressive nuclear congenital cataract. Different haplotypes segregated with the mutation in each family. Conclusions: A recurrent Delta G91CRYBA1/A3 mutation occurs independently in 6.4% of the Chinese families with autosomal dominant nuclear cataracts and most likely represents a mutational hot spot, which underscores the relations between nonprogressive nuclear cataract and CRYBA1/A3.
