Abstract

Kniest syndrome (OMIM #156550) is a rare autosomal dominant disorder caused by a dysfunction of type II collagen, which is encoded by the COL2A1 gene (OMIM +120140) mapped to chromosome 12q13.11. Type II collagen, a molecule found mostly in the cartilage and vitreous tissues, is essential for the normal development of bones and other connective tissues. Kniest syndrome is a type II collagenopathy that presents as skeletal abnormality associated with disproportionate dwarfism, kyphoscoliosis, enlarged joints, visual loss, hearing loss, and cleft palate. This report describes a Korean patient with Kniest syndrome who was diagnosed with typical clinical features and radiologic findings. The patient presented with disproportionately short stature and kyphoscoliosis from birth. A skeletal survey revealed fused lamina in the thoracic spine, hemivertebrae, flexion deformities in multiple joints, and plagiocephaly.
