The disease is characterized by Perthes-like pelvic anomalies (premature closure of the capital femoral epiphyses and widened femoral necks with flattened femoral heads), enchondromata and ecchondromata.


Upington disease has an autosomal dominant pattern of inheritance.

Upington disease is inherited in an autosomal dominant manner.[3][4] This means the defective gene is located on an autosome, and one copy of the defective gene is sufficient to cause the disorder, when inherited from a parent who has the disorder.


The name Upington refers to the district of Cape Province, South Africa from where the family originates.[1]
