Background: Predisposition is responsible for approximately 50% of age-related cataracts. Investigation of inherited forms of cataract provides the opportunity to identify the genes that may play a role in age-related cataract as well.

Patients and methods: We describe the phenotype of a Swiss family with juvenile cataract, associated with microcornea and renal glucosuria. 11 of 17 family members in three generations underwent ophthalmic assessment and urine analysis. Medical records or questionnaires were evaluated in the remaining six cases.

Results: Eleven family members had progressive juvenile cataract. Eight affected members available for clinical examination had bilateral microcornea, not associated with microphthalmos. Furthermore, renal glucosuria was demonstrated in six of these persons. The mode of inheritance is autosomal-dominant.

Conclusions: We have defined a new syndrome, consisting of the association of juvenile cataract, microcornea and renal glucosuria. The pattern of inheritance is autosomal-dominant. Genotyping is ongoing.
