Vitamin D level is dependent on various factors such as sunlight exposure and nutrition. But also on genetic factors. We, therefore, hypothesize that single nucleotide polymorphisms (SNPs) within the vitamin D pathway-related genes could contribute to muscle mass and function via an impact on vitamin D level. However, the integration of studies investigating these issues is still missing. Therefore, this review aimed to systematically identify and summarize the available evidence on the association between SNPs within vitamin D pathway-related genes and vitamin D status as well as various muscle traits in healthy adults. The review has been registered on PROSPERO and was conducted following PRISMA guidelines. In total, 77 studies investigating 497 SNPs in 13 different genes were included, with significant associations being reported for 59 different SNPs. Variations in GC, CYP2R1, VDR, and CYP24A1 genes were reported most frequently, whereby especially SNPs in the GC (rs2282679, rs4588, rs1155563, rs7041) and CYP2R1 genes (rs10741657, rs10766197, rs2060793) were confirmed to be associated with vitamin D level in more than 50% of the respective studies. Various muscle traits have been investigated only in relation to four different vitamin D receptor (VDR) polymorphisms (rs7975232, rs2228570, rs1544410, and rs731236). Interestingly, all of them showed only very low confirmation rates (6\u201317% of the studies). In conclusion, this systematic review presents one of the most comprehensive updates of the association of SNPs in vitamin D pathway-related genes with vitamin D status and muscle traits in healthy adults. It might be used for selecting candidate SNPs for further studies, but also for personalized strategies in identifying individuals at risk for vitamin D deficiency and eventually for determining a potential response to vitamin D supplementation.<\/jats:p>","DOI":"10.3390\/nu13093109","type":"journal-article","created":{"date-parts":[[2021,9,6]],"date-time":"2021-09-06T13:18:26Z","timestamp":1630934306000},"page":"3109","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":66,"title":["Association between Polymorphisms in Vitamin D Pathway-Related Genes, Vitamin D Status, Muscle Mass and Function: A Systematic Review"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2586-0934","authenticated-orcid":false,"given":"Ermira","family":"Krasniqi","sequence":"first","affiliation":[{"name":"Research Platform Active Ageing, University of Vienna, Althanstra\u00dfe 14, 1090 Vienna, Austria"},{"name":"Centre for Sport Science and University Sports, University of Vienna, Auf der Schmelz 6, 1150 Vienna, Austria"},{"name":"Department of Nutritional Sciences, University of Vienna, Althanstra\u00dfe 14, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4343-9366","authenticated-orcid":false,"given":"Arben","family":"Boshnjaku","sequence":"additional","affiliation":[{"name":"Centre for Sport Science and University Sports, University of Vienna, Auf der Schmelz 6, 1150 Vienna, Austria"},{"name":"Faculty of Medicine, University \u201cFehmi Agani\u201d in Gjakova, Ismail Qemali n.n., 50000 Gjakov\u00eb, Kosovo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1683-7265","authenticated-orcid":false,"given":"Karl-Heinz","family":"Wagner","sequence":"additional","affiliation":[{"name":"Research Platform Active Ageing, University of Vienna, Althanstra\u00dfe 14, 1090 Vienna, Austria"},{"name":"Department of Nutritional Sciences, University of Vienna, Althanstra\u00dfe 14, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9061-7914","authenticated-orcid":false,"given":"Barbara","family":"Wessner","sequence":"additional","affiliation":[{"name":"Research Platform Active Ageing, University of Vienna, Althanstra\u00dfe 14, 1090 Vienna, Austria"},{"name":"Centre for Sport Science and University Sports, University of Vienna, Auf der Schmelz 6, 1150 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"585","DOI":"10.1016\/j.beem.2011.05.002","article-title":"The effect of vitamin D on bone and osteoporosis","volume":"25","author":"Lips","year":"2011","journal-title":"Best Pract.
