Upington disease, also called Perthes-like hip disease, enchondromata, ecchondromata, and familial dyschondroplasia,[1][2] is an extremely rare[3] autosomal dominant malformation disorder. It has only one published source claiming its existence in three generations of one family from South Africa.[4]


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 is inherited in an autosomal dominant manner.[4][5] 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 city in the Northern Cape Province, South Africa from where the family originates.[1]
