Chromosome 8q22.1 Duplication Syndrome
Leri pleonosteosis is an autosomal dominant skeletal disorder characterized by flexion contractures of the interphalangeal joints, limited movement of multiple joints, and short, broad metacarpals, metatarsals, and phalanges. Additional features may include chronic joint pain, short stature, bony overgrowths, spinal cord compression, scleroderma-like skin changes, and blepharophimosis.
