Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a rare autosomal dominant disease caused by FOXL2 gene mutations, and it is clinically characterized by an eyelid malformation associated (type I) or not (type II) with premature ovarian failure (POF).
What are the implications of multiple alterations of the forkhead box L2 (FOXL2) gene in blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) patients?
Human patients carrying mutations in the FOXL2 gene display blepharophimosis/ptosis/epicanthus inversus syndrome (BPES), an autosomal dominant disease associated with eyelid defects and premature ovarian failure in females.
Identification of a novel mutation in FOXL2 gene that leads to blepharophimosis ptosis epicanthus inversus and telecanthus syndrome in a Tunisian consanguineous family.
Deletions involving long-range conserved nongenic sequences upstream and downstream of FOXL2 as a novel disease-causing mechanism in blepharophimosis syndrome.
In a Slovene patient with primary amenorrhoea without an association with blepharophimosis/ptosis/epicanthus inversus syndrome (BPES), a novel 30 bp deletion was identified in the FOXL2 gene.
Mutations of FoxL2 are associated with the blepharophimosis/ptosis/epicanthus inversus syndrome characterized with craniofacial defects and premature ovarian failure.
Premature ovarian failure in the autosomal dominant disorder blepharophimosis-ptosis-epicanthus inversus is due to mutations in the gene encoding Forkhead L2 (FOXL2), producing putative truncated proteins.
Germline mutations of the fork-head transcriptional factor forkhead box L2 (FOXL2) predispose embryos to autosomal-dominant blepharophimosis-ptosis-epicanthus inversus syndrome with primary ovarian insufficiency in female patients, but the mechanisms of FOXL2 in ovarian follicular development remain elusive.
Blepharophimosis sequence (BPES) and microcephaly in a girl with del(3) (q22.2q23): a putative gene responsible for microcephaly close to the BPES gene?
High-resolution comparative mapping with human data shows that this DNA segment is the homolog of the human region associated with Blepharophimosis Ptosis Epicanthus inversus Syndrome (BPES) gene located in 3q23.
Previous studies found that the forkhead transcription factor 2 (FOXL2) gene mutations are responsible for both types of blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) but have not established any systematic statistic model for the complex and even contradictory results about genotype-phenotype correlations between them.
