OBJECTIVE: A novel insertion in the forkhead transcription factor 2 (FOXL2) was identified in a Chilean patient with blepharophimosis, ptosis, and epicanthus inversus syndrome associated with premature ovarian failure (BPES type I). A clinical and molecular characterization of a patient with BPES type I was performed.
METHOD: We present a 16-year-old adolescent girl with surgically treated blepharophimosis, ptosis, and epicanthus inversus that was associated with delayed puberty and secondary amenorrhea at the age of 15, indicators that suggested that the patient had BPES type I. The FOXL2 gene was analyzed by sequencing its coding region.
RESULTS: The sequence analysis of the FOXL2 gene revealed a novel heterozygous mutation: an 11 bp duplication (c.901_911dup11) that was predicted to encode a truncated protein (p.Pro305Argfs*54).
CONCLUSIONS: A novel out-of-frame duplication following the polyalanine domain in the FOXL2 gene was identified in a Chilean patient with BPES type I. This study characterized the molecular alterations in FOXL2 and confirmed the diagnosis, thereby providing information to allow for improved genetic counseling for the patient and her family.
