Q p e I1 collagenopathies consist of chondrodysplasias ranging from lethal to mild in severity. A large number of mutations has been found in the COL2A1 gene. Glycine substitutions have been the most common types of mutation. Genotype-phenotype cor- relations in type I1 collagenopathies have not bee
We report on a patient with a skeletal dysplasia characterized by short stature, spondylo-epiphyseal involvement, and brachydactyly E-like changes. This condition has been described as spondyloperiph-era1 dysplasia and the few published cases suggest autosomal dominant inheritance with considerable
The COL2A1 gene was assayed for mutations in genomic DNA from 12 patients with achondrogenesis type II/hypochondrogenesis. The exons and flanking sequences of the 54 exons in the COL2A1 gene were amplified by a series of specific primers using PCR. The PCR products were scanned for mutations by conf
