Other anomalies can be present: long thin hands and feet, ambiguous genitalia, hypertelorism, etc. An autosomal recessive mode of inheritance seems most likely.

Characteristic cranial features include a wide cranial vault, a flat occiput, broad forehead, a small nose with depressed nasal bridge, and orbital hypertelorism.

Characteristic cranial features include a wide cranial vault, a flat occiput, broad forehead, a small nose with depressed nasal bridge, orbital hypertelorism and proptosis.

Affected infants may also have narrow eyelid folds (palpebral fissures), widely spaced eyes (ocular hypertelorism), and drooping of the upper eyelids (ptosis).

Hypertelorism is an abnormally increased distance between two organs or bodily parts, usually referring to an increased distance between the orbits (eyes)–orbital hypertelorism.

Opitz G/BBB syndrome is diagnosed on the basis of clinical findings and is suspected in males with ocular hypertelorism and at least one other of the major findings (hypospadias or LTE abnormalities).

Hypertelorism is an abnormally increased distance between two organs or bodily parts, usually referring to an increased distance between the orbits (eyes), or orbital hypertelorism.
