Cataracts, Anterior Polar 2
Lens opacities are located in the central anterior capsule and cortex. They usually do not interfere significantly with vision.
Most cases probably occur sporadically but multigenerational families have been reported in which the transmission pattern is autosomal dominant. In one family the phenotype was mapped to 17p13 but the gene responsible has not been identified.
Another type (CTAA1) of anterior polar cataract is associated with chromosomal aberrations (115650).
Lens removal is indicated only if these opacities interfere with vision.
