Barber Say syndrome is a very rare condition characterized by the association of excessive hair growth (hypertrichosis), papery thin and fragile (atrophic) skin, outward turned eyelids (ectropion) and a large mouth (macrostomia). It has been described in less than 20 patients in the medical literature. Barber Say syndrome has a variable presentation, with reports of both mild and severe cases. Inheritance has been debated, with qualities suggestive of autosomal dominant and autosomal recessive. A recent study suggests that at least some cases of Barber Say syndrome are caused by dominant mutations in the TWIST2 gene. Treatment remains a challenge for both patients and doctors, and requires a multidisciplinary approach.
