Birk-Barel syndrome

rare

Birk-Barel syndrome is an inherited condition characterized by intellectual disability, hypotonia, hyperactivity, and unusual facial features. The condition is caused by mutations in the KCNK9 gene on chromosome 8. This condition demonstrates dominant inheritance with paternal imprinting, which means that a mutation in the maternal gene will result in disease, but a mutation in the paternal gene will have no effect (imprinted with paternal silencing).
