DNA was extracted and used for sequencing of the exons of<jats:italic>VDR<\/jats:italic>gene using ABI PRISM 3730xi Genetic Analyzer.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold>Weight, BMI, Vit D, LH and FSH levels were higher in the PCOS patients compared to control group, where Vit D level correlated positively and significantly with FSH, in the control, but showed a negative and non-significant correlation in the PCOS patients. Sequencing results showed extensive polymorphisms in both groups, but the differences in the frequencies were not significant. Demographic and hormonal parameters were compared in the different genotypes of the SNPs. Significant differences were ob served in the values of the studied parameters in rs11168276, rs11168266, rs3858733, rs121909790, rs11168265 and rs731236. Vitamin D level was influenced significantly by the genotypes of rs11168265 (AA) (p=0.008), rs11168276 (AA; p=0.018) and rs731236 (CC; p=0.024).<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold>Vitamin D deficiency does not associate with PCOS in Saudi females. Several SNPs are identified in the VDR gene, in normal and PCOS females, but there is no difference in their frequencies between the two groups. The results show that polymorphism in VDR gene influences certain anthropometric and hormonal parameters in PCOS patients. Further detailed studies are required to confirm the associations between VDR and PCOS.<\/jats:p>","DOI":"10.2478\/jomb-2018-0007","type":"journal-article","created":{"date-parts":[[2018,5,11]],"date-time":"2018-05-11T22:16:42Z","timestamp":1526077002000},"page":"415-425","source":"Crossref","is-referenced-by-count":12,"title":["Polymorphic Variations in VDR Gene in Saudi Women with and Without Polycystic Ovary Syndrome (PCOS) and Significant Influence of Seven Polymorphic Sites on Anthropometric And Hormonal Parameters"],"prefix":"10.5937","volume":"37","author":[{"given":"Arwa","family":"Al Thomali","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maha H.","family":"Daghestani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mazin H.","family":"Daghestani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Namik","family":"Kaya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arjumand","family":"Warsy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3964","reference":[{"key":"ref411","first-page":"2015","article-title":"Classic PCOS phenotype is not associated with deficiency of endogenous vitamin VDR gene polymorphisms rs rs rs rs a case -
