A patient with marfanoid habitus was admitted to the General Hospital, Kuala Lumpur in October 1985 for surgical closure of an atrial septal defect. He was suspected to have Marfan Syndrome but there was no involvement of the aorta nor the eye. The clinical features were intermediate between that of the Marfan Syndrome and the Ehler's Danlos Syndrome. It is suggested that this could be a separate distinct entity within the heritable disorders of connective tissue known as the Marfanoid Hypermobility Syndrome.
