Figure 3. Partial sequence of CRYBA1/A3 at exon3. A: Sequence of affected individual (individual III:11). B: Sequence of unaffected individual (individual III:7). In panel A, the heterozygous mutation IVS3+2 T→G was evident at the flanking splicing junction. This was identified in all the affected participants, but was not found in unaffected family members or in the 100 unrelated control subjects.
