Retraction Note: Identification of a novel mutation of the COL2A1 gene in a Chinese family with spondyloepiphyseal dysplasia congenital

To identify potential disease-causing mutation in the COL2A1 gene in a Chinese family with autosomal dominant spondyloepiphyseal dysplasia congenita (SEDC) and to analyze the phenotype–genotype correlation. Complete physical and radiographic examinations of four affected individuals from SEDC family were conducted. Genomic DNA were isolated from peripheral blood leukocytes. All 54 exons and exon–intron boundaries of the COL2A1 gene were...
