BMC Pregnancy and Childbirth volume 20, Article number: 3 (2019)
Items in both categories Pregnancy and Vitamin D Receptor are listed here:
- After lactation Vitamin D levels are low, increased risk of Breast Cancer, vitamin D should decrease risk – Aug 2021
- Gestational Diabetes – increased risk if poor Vitamin D Receptor – 2 Meta-Analyses 2021
- Higher risk of Recurrent Pregnancy Loss if poor Vitamin D Receptor – Feb 2021
- Spontaneous Miscarriage strongly associated with 2 vitamin D genes – March 2020
- Preterm birth associated with many genes, including the Vitamin D Receptor again – Jan 2020

Vitamin D Receptor is associated in over 58 autoimmune studies
The risk of 44 diseases at least double with poor Vitamin D Receptor as of Oct 2019
Vitamin D Receptor Activation can be increased by any of: Resveratrol, Omega-3, Magnesium, Zinc. Quercetin, non-daily Vit D. Curcumin, intense exercise, Ginger, Essential oils, etc Note: The founder of VitaminDWiki uses 10 of the 12 known VDR activators
PRETERM was in the title of 78 VitaminDWiki pages as of Feb 2022

Premature birth is the main cause of mortality in children under 1 year, and vitamin D deficiency during gestation is associated with prematurity. The effects of vitamin D are mediated by its receptor, which is encoded by the VDR gene. VDR variants—such as single nucleotide variation (SNV)—are associated with increased risk of prematurity, but there are conflicting results. We evaluated serum vitamin D concentrations and the frequency of TaqI/A > G, BsmI/C > T, ApaI/C > A, and FokI/A > T VDR variants in mothers and preterm (PTN) and full-term (FTN) newborns.
We conducted a case-control study comprising 40 pairs of mothers and their PTNs (gestational age < 32 weeks and/or weight < 1500 g), and 92 pairs of mothers and FTNs as controls. Genotyping was performed by real-time PCR, and plasma vitamin D concentrations were measured by electrochemiluminescence.
Vitamin D levels were significantly lower in PTN mothers. Genotypes TaqI/GG and BsmI/TT, and haplotypes AAG (TaqI/A-ApaI/A-FokI/G) and GCA (TaqI/G-ApaI/C-FokI/A) were significantly more frequent in PTN mothers, and genotypes TaqI/AG, ApaI/AA, and FokI/AG resulted in significantly lower vitamin D levels. Genotypes BsmI/TT and ApaI/AA were associated with vitamin D deficiency and 2.36 and 7.99 times greater likelihood of PTB, respectively. Vitamin D levels were also lower in PTNs, although it was not statistically significant. Genotypes BsmI/TT, ApaI/AA, and FokI/GG, and haplotype GAG (TaqI/G-ApaI/A-FokI/G) were significantly more frequent in PTNs. Those with FokI/GG genotypes had significantly lower vitamin D levels.
Conclusions: VDR variants contribute to variations in vitamin D concentrations and the increased risk of prematurity.
