title: A novel mutation in the FOXL2 gene in a Chinese family with blepharophimosis, ptosis, and epicanthus inversus syndrome.
abstract: OBJECTIVE
  To screen mutations in the forkhead transcriptional factor 2 gene (FOXL2) in six Chinese families with blepharophimosis, ptosis, and epicanthus inversus syndrome(BPES).
  
  
  METHODS
  PCR amplification and direct sequencing of the FOXL2 coding region in genomic DNA were performed in affected patients and 80 healthy controls. BLAST analysis of the sequence was made on Internet.
  
  
  RESULTS
  A novel 951-953(delC) was found in the two affected patients of a Chinese family with BPES. No mutations were found in the healthy controls. The 951-953(delC) may cause a frameshift mutation after codon 238 that exists downstream of the forkhead domain, resulting in the production of truncated proteins.
  
  
  CONCLUSIONS
  These findings indicated that the 951-953(delC) deletion mutation in the two patients resulted in truncated proteins and hence led to their BPES. To the authors' knowledge, the 951-953(delC) in FOXL2 has not been previously reported.
