The homeodomain transcription factor SHOX is involved in different human short stature syndromes (Turner syndrome, Léri-Weill dyschondrosteosis LWD [MIM 127300] and Langer mesomelic dysplasia [MIM 249700]) and isolated (idiopathic) short stature [MIM 300582] [1], [2], [3], [4], [5], [6], [7]. This evidence concerns the gene SHOX and Langer mesomelic dysplasia.
