Léri–Weill dyschondrosteosis or LWD is a rare pseudo autosomal dominant genetic disorder which results in dwarfism with short forearms and legs ( mesomelic dwarfism) and a bayonet-like deformity of the forearms ( Madelung's deformity). [1]
It is caused by mutations in the short-stature homeobox gene found in the pseudoautosomal region PAR1 of the X and Y chromosomes, at band Xp22.33 or Yp11.32. [2]
SHOX gene deletions have been identified as the major cause of Leri–Weill syndrome. [3]
Leri–Weill dyschondrosteosis is characterized by mesomelic short stature, with bowing of the radius more so than the ulna in the forearms and bowing of the tibia while sparing the fibula.[ citation needed]
Diagnosis is made following genetic blood testing.[ citation needed]
There is currently no known treatment for Leri-Weill dyschondrosteosis.
LWD was first described in 1929 by André Léri and Jean A. Weill. [4] [5]
