VDR and myeloid sarcoma: Mean age at onset of MS did not differ significantly between patients carrying VDR rs2228570 (Fok1) A/A (mean ± SD  = 33.0±11.5 years), A/G (mean ± SD  = 32.4±9.8 years) and G/G genotypes (mean ± SD  = 38.5±24.7 years; p =  n.s. for the comparison of carriers vs non-carriers of variant alleles), and between patients with genotypes VDR rs731236 (Taq1) T/T (mean ± SD  = 32.5±11.5 years), C/T (mean ± SD  = 32.6±10,6 years) and C/C (mean ± SD  = 35.6±10.9 years; p =  n.s. for the comparison of carriers vs non-carriers of variant alleles).
