General Discussion

Baller-Gerold Syndrome is a rare genetic disorder that is apparent at birth (congenital). The disorder is characterized by distinctive malformations of the skull and facial (craniofacial) area and bones of the forearms and hands.

In infants with Baller-Gerold Syndrome, there is premature fusion of the fibrous joints (cranial sutures) between certain bones in the skull (craniosynostosis). As a result, the head may appear unusually short and wide and/or pointed at the top (turribrachycephaly) or relatively triangular in shape (trigonocephaly). Affected infants may also have a prominent forehead; downslanting eyelid folds (palpebral fissures), small, malformed (dysplastic), low-set ears, and/or other craniofacial abnormalities. Baller-Gerold Syndrome is also characterized by underdevelopment (hypoplasia) or absence (aplasia) of the bone on the thumb side of the forearms (radii). In addition, the bone on the "pinky" side of the forearms (ulnae) is unusually short and curved and the thumbs may be underdeveloped or absent. In some cases, additional physical abnormalities and/or mental retardation may also be present. Baller-Gerold Syndrome is thought to be inherited as an autosomal recessive trait.
