1. As with Chondrodysplasia , PHA affected Dexters should not be bred together. 2. Mir-433 has also been associated with a dominantly inherited form of x linked chondrodysplasia . 3. The first experiments involved stretching the bones in the arms and legs of people with chondrodysplasia . 4. The Chondrodysplasia affected Dexters are typically 6 8 inches shorter in height than non-affected Dexters. 5. A DNA test is available to test for the Chondrodysplasia gene by pulling tail hairs from the animal. 6. The malformations include chondrodysplasia ( improper growth of bone and cartilage ), genitalia, and imperforate anus. 7. It was first identified in 1972 as a novel rare genetic disorder sharing similar symptoms with chondrodysplasia punctata. 8. Short-legged dexter cattle are considered to be heterozygous while bull-dog fetuses are homozygous for chondrodysplasia genes. 9. Knockout mice with the Ctgf gene disrupted die at birth due to respiratory stress as a result of severe chondrodysplasia . 10. This condition is also known as arylsulfatase E deficiency, CDPX1, and X-linked recessive chondrodysplasia punctata 1.
