Females are represented by circles and males by squares. Ophthalmologist confirmed affected individuals are colored black. The phenotype exhibits the appearance of pulverulent nuclear cataract (B). The optical section shows lens opacities in the proband. The fetal nucleus and the embryonal nucleus both display white granular opacities (C).
