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 been reported in patients with SMCD, all in the C-terminal globular domain. To address whether mutations in other domains can cause SMCD, we examined the coding region of the COL10A1 gene in DNA samples from six Japanese families affected with SMCD, by direct sequencing. We detected novel mutations in three unrelated SMCD patients; one was a one-base deletion in the C-terminal globular domain and others were de novo missense mutations in the N-terminal globular domain. All three cases revealed a typical clinical phenotype for SMCD. Thus, we have demonstrated that mutations of COL10A1 in regions other than the C-terminal globular domain can cause SMCD, and the results suggest that the N-terminal globular domain also plays an important role in formation of type X collagen.

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
