Mutations within the gene encoding the alpha 1 (X) chain of type X collagen (COL10A1) cause metaphyseal chondrodysplasia type Schmid but not several other forms of metaphyseal chondrodysplasia.
Type X collagen is a homotrimer of alpha 1 (X) chains encoded by the COL10A1 gene. It is synthesised specifically and transiently by hypertrophic chondrocytes at sites of endochondral ossification. Point mutations and deletions in the region of the COL10A1 gene encoding the alpha 1 (X) carboxyl-terminal (NC1) domain have previously been identified in subjects with metaphyseal chondrodysplasia t...
متن کاملA nonsense mutation in the carboxyl-terminal domain of type X collagen causes haploinsufficiency in schmid metaphyseal chondrodysplasia.
Type X collagen is a short-chain homotrimeric collagen expressed in the hypertrophic zone of calcifying cartilage. The clustering of mutations in the carboxyl-terminal NC1 domain in Schmid metaphyseal chondrodysplasia (SMCD) suggested a critical role for this type X collagen domain, but since no direct analysis of cartilage has been conducted in SMCD patients, the mechanisms of type X collagen ...
متن کاملCongenital Adrenal Hyperplasia and Schmid Metaphyseal Chondrodysplasia in a Child
Congenital adrenal hyperplasia (CAH) is a group of hereditary diseases, which are autosomal recessive. CAH occurs due to defect in one of the cortisol coding genes and often clinically presents itself with signs of androgen overproduction. In this article, we report a case of CAH and Schmid metaphyseal dysplasia. Our literature review indicated that this report is the first attempt on CYP11B1 a...
متن کاملFolding and assembly of type X collagen mutants that cause metaphyseal chondrodysplasia-type schmid. Evidence for co-assembly of the mutant and wild-type chains and binding to molecular chaperones.
Schmid metaphyseal chondrodysplasia results from mutations within the COOH-terminal globular domain (NC1) of type X collagen, a short chain collagen expressed in the hypertrophic region of the growth plate cartilage. Previous in vitro studies have proposed that mutations prevent the association of the NC1 domain of constituent chains of the trimer based upon a lack of formation of a trimeric st...
