Léri–Weill dyschondrosteosis

Léri–Weill dyschondrosteosis
Other names: LWD
Léri–Weill dyschondrosteosis is inherited in an autosomal dominant manner

Léri–Weill dyschondrosteosis or LWD is a rare pseudoautosomal 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]

Signs and symptoms

The clinical presentation of this condition is consistent with short stature and wrist deformity[2]

Causes

A Leri-Weill dyschondrosteosis person confirmed by mutation analysis of SHOX gene-heterogygous mutation of c.491G>A (p.W164X) in the SHOX gene

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.[3]

SHOX gene deletions have been identified as the major cause of Leri–Weill syndrome.[4]

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.

Diagnosis

Diagnosis is made following genetic blood testing.

Treatment

In terms of management, there is administration of recombinant human growth hormone. Wrist splints, and ergonomic devices for wrist discomfort.[2]

History

LWD was first described in 1929 by André Léri and Jean A. Weill.[5][6]
