Schimke Immunoosseous dysplasia

Immunoosseous dysplasia of the Schimke type is an autosomal recessive disorder characterized by skeletal abnormalities, T-cell defects, and nephrotic type progressive nephritis. Mutations of the SMARCAL1 gene are responsible for the disease.

Historical Aspects

The disease was first described, when Schimke in 1971 published a case report.[Error: Macro 'ref' doesn't exist]

Clinical Findings

Schimke immunoosseous dysplasia (SIOD) is characterized by bone abnormalities, nephrotic syndrome, and T-cell deficiency. The disproportionate short stature is the result of spondyloepiphyseal dysplasia. Other radiological findings are ovoid and mildly flattened vertebral bodies, small deformed capital femoral epiphyses, and shallow dysplastic acetabular fossae.

The patient are diagnosed with steroid resistant nephrotic syndrome within 5 years after growth retardation becomes obvious. Renal injury develops into end stage renal failure.
