We report on the case of a 17-year-old boy with clinical features compatible with Lowry-Wood syndrome: microcephaly, short stature, multiple epiphyseal dysplasia, tapetoretinal degeneration, and mental retardation. Bilateral restricted elbow extension, knock knees and hip dislocation were also present. Radiographs showed evidence of radial dislocation due to the absence of the radial heads, lateral dislocation of both patellae, multiple epiphyseal dysplasia that was more severe at the proximal femoral epiphyses, and dislocation of both hips with severe hip dysplasia. The patient developed a behavioral disorder at age 15. Conventional karyotyping was normal (46,XY). Molecular karyotyping, performed through array-based competitive genomic hybridization, showed copy number variants that were probably benign. We suggest that multiple joint dislocations, including the patellae, may be a sign of Lowry-Wood syndrome
