membranous cataract

Cataracts 34

Clinical Characteristics
Ocular Features: 

Two families with mutations in the FOXE3 associated with cataracts have been reported.  The lens opacities may be present at birth or found soon thereafter.  In 1 family with 5 affected sibs membranous cataracts were present along with corneal opacities, microcornea and nystagmus.  In another family, 7 sibs had posterior subcapsular cataracts but no other ocular findings.

Systemic Features: 

No systemic abnormalities were associated with the ocular findings.

Genetics

Homozygous mutations in the FOXE3 (1p33) gene segregated with the eye findings in the two families.  FOXE3 is a transcription gene and its mutations are responsible for a variety of ocular abnormalities.

Pedigree: 
Autosomal recessive
Treatment
Treatment Options: 

Surgical cataract removal may be indicated.  Amblyopia is a risk and requires rehabilitation.
