Figure 3. Sequence analysis of the Chinese pedigree with autosomal dominant posterior polar cataract. A splice site mutation at the
first base of intron 3 (G→A) , which is also identified at position 474 in the donor splice junction of intron 3 was co-segrated
with all patients in the family, but was not found in the unaffected family members nor in the 50 unrelated control subjects.
