Summary
The protein encoded by this gene belongs to the albumin gene family. It is a multifunctional protein found in plasma, ascitic fluid, cerebrospinal fluid and on the surface of many cell types. It binds to vitamin D and its plasma metabolites and transports them to target tissues. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Feb 2011]

50 PCOS women and 50 normal women recruited from the Department of Obstetrics and Gynaecology, Vardhman Mahavir Medical College and Safdarjang Hospital (New Delhi, India) 
The present study shows that the GT allele of VDBP SNP rs7041, the VDBP allelic combination (GC1F/1F), and GA allele of CYP2R1 SNP rs2060793 in vitamin D deficient women increase the risk of PCOS. 
VDR 
PCOS, chronic anovulation, manifestations of hyperandrogenism, insulin resistance, obesity, and metabolic syndrome 
 
Rotterdam criteria

191 PCOS women and 100 control women from South of Brazil 
The present study is the first to describe that genotype TT of SNP rs7041 is associated with MetS in PCOS and with lower 25(OH)D levels in both PCOS and healthy controls with regular ovulatory cycles. The polymorphisms rs2282679, rs4588, and rs7041 of the DBP gene, as well as their haplotypes, are not related to PCOS in southern Brazilian women
