Hypothesis

The study aimed to identify the genetic defect in a family with congenital lamellar cataracts.

Conclusion

The mutation P.R339H in the BFSP2 gene is linked to congenital lamellar cataracts in a Chinese family.

Supporting Evidence

  • The mutation cosegregated with the disease phenotype in all affected individuals.
  • The maximum LOD score was 7.22, indicating strong linkage.
  • The mutation was not found in unaffected family members or 100 normal controls.

Takeaway

A family with cataracts was studied, and scientists found a new gene change that causes the cataracts.

Methodology

Genotyping, linkage analysis, and sequencing were performed on family members.

Participant Demographics

Four-generation Chinese family with 17 affected individuals.
