Abstract

Objective: To evaluate the growth disorder and phenotype in prepubertal children with Leri-Weill dyschondrosteosis (LWD), a dominantly inherited skeletal dysplasia, and to compare the findings from girls with Turner syndrome (TS). Study design: We studied the auxologic and phenotypic characteristics in 34 prepubertal LWD subjects (ages 1 to 10 years; 20 girls, 14 boys) with confirmed short stature homeobox-containing gene (SHOX) abnormalities. For comparative purposes, we evaluated similar physical and growth parameters in 76 girls with TS (ages 1 to 19 years) and 24 girls with LWD (ages 1 to 15 years) by using data collected from the postmarketing observational study, GeNeSIS. Results: In the clinic sample LWD subjects, height standard deviation score ranged from -5.5 to +0.1 (-2.3 ± 1.3, girls and -1.8 ± 0.6, boys). Wrist changes related to Madelung deformity were present in 18 of 34 (53%) LWD subjects. In comparing the LWD and TS populations in the GeNeSIS sample, Madelung deformity, increased carrying angle, and scoliosis were more prevalent in the LWD population, whereas high arched palate was similarly prevalent in the two populations. Conclusions: Short stature is common in both LWD (girls and boys) and TS (girls). Clinical clues to the diagnosis of SHOX haploinsufficiency in childhood include short stature, short limbs, wrist changes, and tibial bowing.
