Cataracts 43 Clinical CharacteristicsOcular Features: Cataracts apparently are diagnosed at variable ages but likely have a juvenile or earlier age of onset. One patient in the Danish multigenerational family was diagnosed at age 18 years but was not operated upon until age 45. The lens opacities in this individual were located centrally and in the posterior subcapsular region. Virtually no clinical information is available since other patients in this family had previously had cataract surgery and the lens phenotype could not be determined. No other ocular abnormalities were reported. Systemic Features: No systemic abnormalities have been reported. GeneticsA single Danish family with 9 affected members in 3 generations has been reported. Heterozygous mutations in UNC45B gene (17q12) are most likely responsible but other candidate genes have not been completely ruled out. Pedigree: Autosomal dominantTreatmentTreatment Options: Cataract surgery may be required.
