A case of mandibulofacial dysostosis (Treacher Collins syndrome) is pr
esented. Clinical features and skull radiographs revealed typical anom
alies associated with the syndrome. Cleft of the soft palate and uneru
pted multiple supernumerary teeth were present in this case. No haemat
ological, biochemical or immunological abnormalities could be detected
in the patient. Pedigree analysis showed an autosomal dominant mode o
f transmission of the disease. Chromosomal studies did not reveal any
structural or numerical discrepancies.
