Is BPES - Blepharophimosis Ptosis Epicanthus Inversus Syndrome contagious?

BPES (Blepharophimosis Ptosis Epicanthus Inversus Syndrome) is not contagious and cannot be spread through touch, proximity, or any form of social contact. It is a rare genetic condition caused by mutations in the FOXL2 gene, meaning it is biologically impossible to "catch" it from another person.

What is the cause of BPES?

Blepharophimosis Ptosis Epicanthus Inversus Syndrome is a congenital condition, meaning it is present from birth. It is caused by a mutation in the FOXL2 gene located on chromosome 3. Because BPES is strictly genetic, it is passed down through families in an autosomal dominant pattern, or it can occur as a new (de novo) mutation in an individual with no previous family history. It is never caused by viruses, bacteria, or environmental pathogens.

Why is there confusion regarding contagion?

Because the physical characteristics of BPES—such as narrow eyelid openings (blepharophimosis), drooping eyelids (ptosis), and skin folds near the inner eye (epicanthus inversus)—are visible from birth, individuals may sometimes face unfounded social stigma. Misunderstandings often arise because rare physical differences are sometimes incorrectly associated with infectious eye conditions like conjunctivitis ("pink eye"). It is vital to emphasize that BPES involves structural differences in the eyelid anatomy, not an active infection, and poses zero risk to those in contact with a person living with the condition.

Are there environmental triggers for BPES?

There are no environmental triggers that cause or worsen the manifestation of Blepharophimosis Ptosis Epicanthus Inversus Syndrome. The condition is entirely determined by an individual's genetic code. While some individuals with BPES may experience secondary eye irritation due to the structural shape of their eyelids, this is a mechanical issue related to eyelid closure and not a contagious or environmentally triggered illness.

Facts about BPES genetics

• Inheritance: Autosomal dominant (a 50% chance of passing the gene to offspring).


• Genetic Locus: 3q22.3 (the location of the FOXL2 gene).


• Clinical Types: Type I (associated with premature ovarian insufficiency in females) and Type II (limited to eyelid anomalies).
