Metachondromatosis has an autosomal dominant pattern of inheritance.

Metachondromatosis is an autosomal dominant[1]incompletely penetrant[2]skeletal disorder affecting the growth of bones, leading to multiple enchondromas and osteochondromas.[2] This tumor syndrome affects mainly tubular bones, though it can also involve the vertebrae, small joints, and flat bones.[3]

Genetics


Metachondromatosis is inherited in an autosomal dominant manner.[2] This means that the defective gene responsible for a disorder is located on an autosome, and only one copy of the gene is sufficient to cause the disorder, when inherited from a parent who has the disorder.


It has been associated with PTPN11.[2]
