Over the past few years, there has been a notable increment in scientific literature aimed at unraveling the genetic foundations of vitamin D signaling and its implications for susceptibility to autoimmunity, however, most of them address isolated diseases. Here, we conducted a systematic review of genetic variants related to vitamin D and autoimmune diseases and we discussed the current landscape of susceptibility and outcomes. Of 65 studies analyzed, most variants cited are in vitamin D binding protein (VDBP; rs2282679 GC gene), 25-hydroxylase (rs10751657 CYP2R1), 1α-hydroxylase (rs10877012, CYP27B1) and the nuclear hormone receptor superfamily [FokI (rs2228570), BsmI (rs1544410), ApaI (rs7975232), and TaqI (rs731236) in VDR gene]. Therefore, our findings confirmed the associations of several genetic variants of vitamin D signaling with a broad spectrum of autoimmune diseases/traits. In addition, given the low number of papers found with functional analysis, further studies to elucidate the real effect that the variants exert on Vitamin D signaling are recommended.

Vitamin D blood test misses a lot

• Vitamin D from coming from tissues (vs blood) was speculated to be 50% in 2014, and by 2017 was speculated to be 90%
• Note: Good blood test results (> 40 ng) does not mean that a good amount of Vitamin D actually gets to cells
• A Vitamin D test in cells rather than blood was feasible (2017 personal communication)   Commercially available 2019
  • However, test results would vary in each tissue due to multiple genes
• Good clues that Vitamin D is being restricted from getting to the cells
  1) A vitamin D-related health problem runs in the family
      especially if it is one of 51+ diseases related to Vitamin D Receptor
  2) Slightly increasing Vitamin D shows benefits (even if conventional Vitamin D test shows an increase)
  3) DNA and VDR tests - 100 to 200 dollars $100 to $250
  4) PTH bottoms out ( shows that parathyroid cells are getting Vitamin d)
     Genes are good, have enough Magnesium, etc.
  5) Back Pain
     probably want at least 2 clues before taking adding vitamin D, Omega-3, Magnesium, Resveratrol, etc

What can be done if have a poor CYP27B1

• Larger doses of Vitamin D
• More Bio-available: Gut-friendly form, Topical form, taken with fatty meal, taken with evening meal
• Additional sources: UV
• Increase Vitamin D metabolism: additional Magnesium, Omega-3
  • All cytochrome P450 enzymes require Mg++ as a cofactor
• Increase the amount of Vitamin D in the blood that gets to cells: increase activation of VDR
  • See: Reasons for low response to vitamin D
