Vitamin D binding protein (DBP) is one of regulators of vitamin D serum levels. rs4588 and rs7041 polymorphisms of the DBP gene constitute the genetic basis of the three major isoforms of circulating DBP, called GC1s, GC1f and GC2. We evaluated the association between the rs4588, rs7041, rs2282679 SNPs and of DBP isoforms with DBP and 25(OH)D serum levels and investigated whether these gene variants influence on the presence of vitamin D deficiency in a non-selected women sample. In this cross-sectional study, bio-repository samples of 443 apparently healthy women aged 20 to 72 years were analyzed. Most of the participants were ppostmenopausal (n=359). Sufficient circulating levels of 25(OH)D was considered as ≥20ng/mL and deficiency as
