A genomic deletion encompassing CRYBB2-CRYBB2P1 is responsible for autosomal recessive congenital cataracts
Abstract Here we report a consanguineous Pakistani family with multiple affected individuals with autosomal recessive congenital cataract (arCC). Exclusion analysis established linkage to chromosome 22q, and Sanger sequencing coupled with PCR-based chromosome walking identified a large homozygous ge...

description | Abstract Here we report a consanguineous Pakistani family with multiple affected individuals with autosomal recessive congenital cataract (arCC). Exclusion analysis established linkage to chromosome 22q, and Sanger sequencing coupled with PCR-based chromosome walking identified a large homozygous genomic deletion. Our data suggest that this deletion leads to CRYBB2-CRYBB2P1 fusion, consisting of exons 1–5 of CRYBB2 and exon 6 of CRYBB2P1, the latter of which harbors the c.463 C > T (p.Gln155*) mutation, and is responsible for arCC. |
