Interpretive Summary: Vitamin D deficiency has been linked to many health conditions, including obesity and its outcomes cardiovascular disease and cancer. Levels of Vitamin D in the blood are influenced by many factors including sun exposure, age, dietary intake of certain foods such as fortified dairy products and oily fish, supplements, and genetic factors, but the genetic reasons why some individuals have higher (better) levels of blood Vitamin D than others are poorly understood. To address this problem, we analyzed genetic variation across the whole genome to look for locations where genetic differences associate with differences in Vitamin D levels. We confirmed three known genetic loci, validated one suspected genetic locus, and identified two new genetic loci associated with Vitamin D levels. This work is of importance to other scientists who can use this information to identify the biological pathways explaining why some people have higher Vitamin D in their blood than others. Eventually, this subsequent information may help us design new interventions or therapeutic options for raising Vitamin D in the blood, which should be of interest to those at risk of obesity and cardiovascular disease, as well as their care providers.

Technical Abstract: Vitamin D is a steroid hormone precursor that is associated with a range of human traits and diseases. Previous GWAS of serum 25-hydroxyvitamin D concentrations have identified four genome-wide significant loci (GC, NADSYN1/DHCR7, CYP2R1, CYP24A1). In this study, we expand the previous SUNLIGHT Consortium GWAS discovery sample size from 16,125 to 79,366 (all European descent). This larger GWAS yields two additional loci harboring genome-wide significant variants (P=4.7×10-9 at rs8018720 in SEC23A, and P=1.9×10-14 at rs10745742 in AMDHD1). The overall estimate of heritability of 25-hydroxyvitamin D serum concentrations attributable to GWAS common SNPs is 7.5%, with statistically significant loci explaining 38% of this total. Further investigation identifies signal enrichment in immune and hematopoietic tissues, and clustering with autoimmune diseases in cell-type-specific analysis. Larger studies are required to identify additional common SNPs, and to explore the role of rare or structural variants and gene–gene interactions in the heritability of circulating 25-hydroxyvitamin D levels.
