An allelic variation of the COL9A2 gene encoding the alpha(2)-chain of collagen IX has recently been identified as a genetic risk factor for intervertebral disc prolapse, resulting in a tryptophane (Trp) substitution at position 326 of the protein. To enable quick screening of a large population we established a single enzyme (BsmFI) restriction assay which was validated by screening disc tissue samples of 250 patients (age, 47.1 +/- 13.7 years). Positive results were confirmed by nucleotide… CONTINUE READING
