PG - 937-8; discussion 939 AB - STUDY DESIGN: The human leukocyte antigen (HLA) haplotypes in families of patients with known ossification of the posterior longitudinal ligament (OPLL) were reviewed. OBJECTIVE: To clarify how genetic factors relate to the development of OPLL. SUMMARY OF BACKGROUND DATA: The association between genetic factors and the development of OPLL is still unknown. MATERIALS AND METHODS: The association between HLA haplotypes and OPLL was studied in families of 24 patients with OPLL. RESULTS: The prevalence of OPLL was higher in the siblings showing a higher share of identical HLA haplotypes: 10 (53%) of 19 with concurrence of two strands, and 5 (24%) of 21 with concurrence of one strand. Of 21 subjects who had no HLA haplotype identical with that in OPLL patients, only one showed evidence of OPLL. CONCLUSION: Genetic factors predispose toward the development of OPLL.
