Spondyloepiphyseal dysplasia congenita is an inherited disorder of bone growth that affects the bones of the spine and ends of the long bones in the arms and legs. Features of this condition include short stature (dwarfism); a very short trunk and neck; abnormal curvature of the spine; barrel-shaped chest; shortened limbs; an abnormality of the hip joint; and problems with vision and hearing. Arthritis and decreased joint mobility often develop early in life. More than 175 cases have been reported in the scientific literature. This condition is caused by mutations in the COL2A1 gene and is inherited in an autosomal dominant pattern. Most cases result from new mutations in the gene and occur in people with no family history of the condition.[1]
