title: Clinical and radiological characteristics of 22 children with SHOX anomalies and familial short stature suggestive of Léri-Weill Dyschondrosteosis.
abstract: OBJECTIVE
  To describe genetic, clinical, anthropometric and radiological characteristics of 22 children with SHOX gene anomalies and familial short stature suggestive of Léri-Weill dyschondrosteosis.
  
  
  METHODS
  Monocentric retrospective observational study.
  
  
  RESULTS
  Six children (27%) presented with deletions located downstream of SHOX (mean height -1.4 ± 0.9 SDS) and 16 (68%) with either deletions encompassing SHOX, intragenic deletions or point mutations of SHOX (mean patient height for the 3 latter types of anomalies: -2.6 ± 0.8 SDS). In our sample, the two most frequently observed dysmorphic signs were clinical and/or radiological Madelung deformity (86%) and high arched palate (77%). Half the girls were born small for gestational age. Sixteen children treated with recombinant growth hormone had an increase in height from -2.7 ± 0.7 to -1.4 ± 0.7 SDS. Four children achieved adult height (-2.0 ± 0.9 SDS) with a gain over baseline height of 1.0 ± 0.5 SDS after a mean treatment duration of 5.8 ± 2.1 years.
  
  
  CONCLUSIONS
  Patients shared common clinical, anthropometric and radiological signs but their height deficit varied, depending on the type of the SHOX gene anomaly. Due to the small size of our sample, our findings need to be confirmed in a larger population of patients.
