Cataracts, Anterior Polar 2

Clinical Characteristics
Ocular Features: 

Lens opacities are located in the central anterior capsule and cortex.  They usually do not interfere significantly with vision.

Systemic Features: 



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).

Yet another form of autosomal dominant anterior polar cataract is associated with corneal disease (Cataracts, Anterior Polar with Guttata) (121390).

Other cataracts that map to chromosome 17 are zonular sutural cataract (600881) with a locus at 17q11-q12 and cerulean or ‘blue dot’ cataract (115660) at 17q24.

Autosomal dominant
Treatment Options: 

Lens removal is indicated only if these opacities interfere with vision.
