Retinoic acid receptor agonists can have dramatic negative effects on growth and even induce premature growth cessation and epiphyseal fusion (1, 2). An 11 5/12-year-old, prepubertal girl with fibrodysplasia ossificans progressiva presented in our pediatric skeletal disorders clinic with the concern of early growth cessation. She had participated in a clinical trial of Palovarotene (“MOVE”, NCT03312634), a retinoic acid receptor-gamma agonist, since the age of 9 10/1...

Objectives: Heterozygous mutations in the aggrecan gene (ACAN) are associated with idiopathic short stature, with or without advanced bone age (BA), osteochondritis dissecans (OCD) and early onset of severe osteoarthritis (OA). Variable features also include midface hypoplasia, brachydactyly, short thumbs and intervertebral disc degenerative disease.Methods: We reviewed 173 radiographs in 22 individuals (8F:14M), (three shoulders, 10 hands, 10 w...
