Schmid metaphyseal chondrodysplasia (SMCD) is a relatively common, heritable osteochondrodysplasia characterized by short-limbed short stature with normal facies, and generalized metaphyseal dysplasias of the long and short tubular bones. Several mutations of the type X collagen gene (COL10A1) have
## Abstract Both dominantβnegative and haploinsufficiency effects have been proposed in the pathogenesis of metaphyseal chondrodysplasia type Schmid (MCDS) due to nonsense and frameβshift mutations of __COL10A1__. This study examines these alternative effects. A proband with typical earlyβonset MCD
Schmid metaphyseal chondrodysplasia (SMCD) has previously been shown to be the result of mutations in the type X collagen gene, COLlOAl. A further three mutations have been identified, including two nonsense mutations (YZ68X, W651X) and a frameshift mutation (1856delCC). Each of the 10 SMCD mutation
