Disease IDSourceNameDescription
600204 OMIMMultiple epiphyseal dysplasia 2 (EDM2)A generalized skeletal dysplasia associated with significant morbidity. Joint pain, joint deformity, waddling gait, and short stature are the main clinical signs and symptoms. Radiological examination of the skeleton shows delayed, irregular mineralization of the epiphyseal ossification centers and of the centers of the carpal and tarsal bones. Multiple epiphyseal dysplasia is broadly categorized into the more severe Fairbank and the milder Ribbing types. The Fairbank type is characterized by shortness of stature, short and stubby fingers, small epiphyses in several joints, including the knee, ankle, hand, and hip. The Ribbing type is confined predominantly to the hip joints and is characterized by hands that are normal and stature that is normal or near-normal. The disease is caused by variants affecting the gene represented in this entry.
614284 OMIMStickler syndrome 5 (STL5)An autosomal recessive form of Stickler syndrome, an inherited disorder that associates ocular signs with more or less complete forms of Pierre Robin sequence, bone disorders and sensorineural deafness. STL5 is characterized by high myopia, vitreoretinal degeneration, retinal detachment, mild to moderate sensorineural hearing loss, short stature in childhood, and absence of cleft palate and Pierre Robin sequence. The disease is caused by variants affecting the gene represented in this entry.
603932 OMIMIntervertebral disc disease (IDD)A common musculo-skeletal disorder caused by degeneration of intervertebral disks of the lumbar spine. It results in low-back pain and unilateral leg pain. Disease susceptibility is associated with variants affecting the gene represented in this entry.
