What is Bijlsma (1980) - Mr; Cleft Palate; Aqueduct Stenosis; Contractures?

Bijlsma (1980) - Mr; Cleft Palate; Aqueduct Stenosis; Contractures is a rare disease.
There are currently no additional known synonyms for this rare genetic disease.

The original case report is difficult to interpret. The child had a cleft palate, a hypoplastic mandible, long slender fingers with a flexion contracture of the left 3rd finger, and club feet. At 5 years of age he was spastic and was significantly retarded. At that stage he was thought to have in addition large ears, myopia, narrow palpebral fissures, a broad nasal bridge and a narrow nose with hypoplastic alae nasi. An AEG showed hydrocephalus with aqueduct stenosis. The father had camptodactyly and the mother had a cleft lip. The author states that there is a strong family history of similar physical abnormalities in the parents but other than those mentioned no further detail is given.
A ten year old Mexican girl with similar features was reported by Boles (1999). CT scan just showed prominence of the lateral ventricles.

NOTE - the original Bijlsma (1980) patient has now been shown to have a chromosomal abnormality (deletion of 18q and trisomy 20p) - personal commnunication - Raoul Hennekam and Jeannette Hoogeboom(2009).
