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.

对 79,366 名欧洲血统个体进行的全基因组关联研究揭示了 25-羟基维生素 D 水平的遗传结构。



维生素 D 是一种类固醇激素前体,与一系列人类特征和疾病有关。先前对血清 25-羟基维生素 D 浓度的 GWAS 已鉴定出四个全基因组显着位点(GC、NADSYN1/DHCR7、CYP2R1、CYP24A1)。在这项研究中,我们将之前 SUNLIGHT Consortium GWAS 发现的样本量从 16,125 扩大到 79,366(均为欧洲血统)。这个更大的 GWAS 产生了两个额外的基因座,其中包含全基因组显着变异(SEC23A 中 rs8018720 处的 P = 4.7×10 -9 ,AMDHD1 中 rs10745742 处的 P = 1.9×10 -14 )。 GWAS 常见 SNP 引起的 25-羟基维生素 D 血清浓度遗传力的总体估计为 7.5%,统计上显着的位点解释了总数的 38%。进一步的研究确定了免疫和造血组织中的信号富集,以及细胞类型特异性分析中与自身免疫性疾病的聚类。需要更大规模的研究来确定其他常见的 SNP,并探索罕见或结构变异以及基因间相互作用在循环 25-羟基维生素 D 水平遗传性中的作用。
