Leri's pleonosteosis is a rare rheumatic condition. It was first described by the French physician Leri in 1921.[1]
Presentation[edit]
The clinical features of this condition include[citation needed]
- Flattened facial features
- Flexion contractures of the interphalangeal joints of hand and foot.
- Limited motion of multiple joints
- Short broad metacarpals, metatarsals and phalanges
Thickening of the skin may occur in a fashion similar to that occurs in scleroderma. The thumbs may be angled in a lateral direction (valgus deformity). The knees may be angled backwards (genu recurvatum). Abnormalities of the upper spinal cord may also occur.[citation needed]
Genetics[edit]
It is inherited in an autosomal dominant fashion.[citation needed]The pathogenesis of this condition appears to be due to over expression of two genes - GDF6 and SDC2.[2] These genes are located on the long arm of chromosome 8(8q22.1).
