Hajdu-Cheney disease
Also known as:
Cheney’s dentoarthro-osteo dysplasia
Cheney-Hajdu syndrome
Giaccai’s syndrome 1
Hajdu's syndrome
Synonyms:
Acro-osteolysis syndrome, acro-osteolysis type Hajdu-Cheney, acro-osteolysis-osteoporosis-skull changes, arthrodento-osteodysplasia, cranio-skeletal dysplasia, inheritable idiopathic osteolysis type VI.
Associated persons:
William D. Cheney
Leonardo Giaccai
Nicholas Hajdu
Description:
A hereditary condition characterized by stunted stature, wormian bones, slowly progressive skeletal dysplasia which affects the skull, spine, and long bones, loss of the terminal phalanges of the hands and feet sometimes giving the appearance of clubbing with osteoporosis. Resorption of the alveolar process and early loss of teeth are the principal dental features. Joint laxity is a frequent feature.
Bone fractures from minor traumas. Both sexes affected. Aetiology unknown. Inheritance is autosomal dominant. Sporadic cases are believed to represent a fresh gene mutation.
An early description of single cases was made in 1948 by Hajdu and Ralph Kauntze [London]. In 1965 Cheney recognized the genetical character of the disturbance.
