Acromesomelic Dysplasia, Maroteaux Type; Amdm

Description

The Maroteaux type of mesomelic sysplasia is an autosomal recessive disorder characterized by severe dwarfism (height below 120 cm) with shortening of the middle and distal segments of the limbs. This condition is usually diagnosed at birth and becomes more obvious in the first 2 years of life. X-rays show short broad fingers, square flat feet, and shortening of the long bones (particularly the forearms). The radius is bowed; the ulna is shorter than the radius, and its distal end is occasionally hypoplastic. The skull is dolichocephalic and a shortness of the trunk, with decreased vertebral height and narrowing of the lumbar interpedicular distances, is consistently observed. Facial appearance and intelligence are normal (summary by Faivre et al., 2000).
