IV4	22	Female	12		Bilateral punctate, asteroidal (above the posterior pole) cataracts
IV8	19	Male	10		Bilateral coronary, punctate cataracts
IV10	24	Female	15		Bilateral coronary, inverted T-shaped (posterior pole) cataracts
IV15	13	Male			Bilateral sparse punctate, asteroidal (above the posterior pole) cataracts
IV16	6	Male			Sparse punctate opacities

Before the age of 10, no clinical features were manifest (IV16); punctate opacification was primarily scattered in the lens perimeter, causing almost no influence on the life of the affected individuals. In adolescence, affected individuals showed ambiguous visual clinical features. At about the age of 30, the clinical features became serious. Two affected family members (III4, III23) had different clinical features between their two lenses; III1, III2, III22, and IV10 had different clinical features from each other. The clinical features of III22, IV1, and IV4 were similar.
