متن کاملCOL10A1 nonsense and frame-shift mutations have a gain-of-function effect on the growth plate in human and mouse metaphyseal chondrodysplasia type Schmid.
Missense, nonsense and frame-shift mutations in the collagen X gene (COL10A1) result in metaphyseal chondrodysplasia type Schmid (MCDS). Complete degradation of mutant COL10A1 mRNA by nonsense-mediated decay in human MCDS cartilage implicates haploinsufficiency in the pathogenesis for nonsense mutations in vivo. However, the mechanism is unclear in situations where the mutant mRNA persist. We s...
متن کاملMutations 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 کاملIdentification of key genes associated with Schmid-type metaphyseal chondrodysplasia based on microarray data
This study aimed to gain a better understanding of the molecular circuitry of Schmid-type metaphyseal chondrodysplasia (SMCD), and to identify more potential genes associated with the pathogenesis of SMCD. Microarray data from GSE72261 were downloaded from the NCBI GEO database, including collagen X p.Asn617Lys knock-in mutation (ColXN617K), ablated XBP1 activity (Xbp1CartΔEx2), compound mutant...
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...
