Genetic factors seem to play a role in symptomatic lumbar disc disease (LDD). It has been shown previously that a tryptophan mutaion of the Col9A2 gene is a major risk factor for LDD in a Finish population. The impact of collagen gene variations on the relapse rate after lumbar discectomy, however, has not been studied so far. We conducted a genotyping study of patients who underwent lumbar discectomy to determine the influence of Col9A2 variation on the recurrence rates. 288 biopsy samples were analyzed by PCR restriction fragment analysis and direct sequencing. The results showed a significant higher frequenz for homozygous arginin allele of Col9A2 in the patient group with early recurrence. In contrast, the tryptophan mutation could not be found in the analysis.
