Osteochondrodysplasia and Achondroplasia in Cats
Osteochondrodysplasia is a growth and developmental abnormality
of the bone and cartilage, which results in lack of normal bone
growth and bone deformities. Where osteo refers to the bone,
chondro refers to the cartilage, and dysplasia is a general term
that is applied to abnormal growth. The Scottish fold breed has
been found to be predisposed to osteochondrodysplasia of the
limbs. Achondroplasia is a form of osteochondrodysplasia in
which the bones do not grow to the normal size, based on what is
expected of the breed. This is caused by a mutation of the
fibroblast growth factor receptor gene. The result is abnormally
short limbs, a condition called dwarfism. In some breeds this
trait is selectively encouraged, such as with the Munchkin
breed. These disorders are genetically acquired. Symptoms and
