Our findings that the increased risk of GCA was found among alcohol drinking and younger patients (<60 years of age) who carried VDR rs1989969 C>T genotype and the reduced risk of GCA for man with VDR Trs2107301Trs2228570Crs1989969Grs11568820 haplotype, should be interpreted with much caution. Here, VDR is linked to temporal arteritis.
