Figure 4. Mutation analysis of CRYAB. Sequence chromatograms of the partial fragment (363 bp) of CRYAB in one unaffected individual of the autosomal dominant congenital cataract (ADCC) family demonstrated a nucleotide sequence encoding Arg (R) at codon 11. Sequence chromatograms of one affected individual demonstrate a G to A transition resulting in an amino acid substitution of Arg by His.
