Cataracts 45

Clinical Characteristics

Ocular Features:

Dense white cataracts have been diagnosed as soon as 2 weeks after birth.

Systemic Features:

No dysmorphic features or psychomotor deficits have been found.

Genetics

Homozygous mutations in the SIPA1L3 [1] gene (19q13.1-q13.2) were found in a consanguineous German family in which 2 of 3 female sibs were affected. The parents were phenotypically normal but heterozygous for the mutation.

Treatment

Treatment Options:

Surgical removal has apparently been successful.
