- Braham-Lenz syndrome
- Lenz-Majewski hyperostotic dwarfism
A very rare syndrome of multiple congenital anomalies, mental retardation, and progressive skeletal sclerosis. Characterised by progeria, growth retardation, vein dilatation, large anterior fontanelle, emaciation, large ears (choanal atresia), hands and feet syndactyly, joint hyperextension, and dental enamel hypoplasia.
Only two cases reported (1990). Present from birth. The syndrome is believed to be transmitted as an autosomal dominant trait.
R. L. Braham in 1969 described it as Camurati-Engelmann syndrome. Lenz and Majewski in 1974 delimitated the disease picture as an independent entity.
