Insights

Cri du chat syndrome, a genetic disorder, can be associated with congenital cataracts. This case highlights a balanced translocation in a mother passing the condition to her infant, who received cataract treatment.

Area of Science:

  • Genetics
  • Ophthalmology
  • Pediatrics

Background:

  • Cri du chat syndrome is a genetic disorder caused by a deletion on the short arm of chromosome 5.
  • Congenital cataracts are clouding of the lens present at birth.
  • The association between cri du chat syndrome and congenital cataracts is not widely established.

Observation:

  • An 11-month-old infant diagnosed with cri du chat syndrome presented with bilateral congenital cataracts.
  • The chromosomal abnormality, a balanced 5/11 translocation, was inherited from a phenotypically normal mother.
  • The infant underwent surgical intervention for cataracts and was fitted with contact lenses.

Findings:

  • This case demonstrates a potential link between cri du chat syndrome and congenital cataracts.
  • Balanced chromosomal translocations can lead to genetic disorders and associated phenotypes in offspring.
  • Early intervention for congenital cataracts in infants with genetic syndromes is crucial.

Implications:

  • Genetic counseling is important for carriers of balanced translocations.
  • Further research is warranted to explore the prevalence and mechanisms of cataracts in cri du chat syndrome.
  • This case underscores the importance of comprehensive ophthalmological evaluations in infants with genetic syndromes.
