Gene problem discovered by taking Vitamin D, sibling had same gene problem – Dec 2019

Example of gene problem running in a family
CYP24A1 problem allowed Vitamin D to accumulate in the body, resulting in hypercalcemia.
It was discovered that a sibling had the same gene problem

• Vitamin D Heritability: twin studies – 20 percent to 85 percent, GWAS 5 percent – Oct 2018
• Health problems that run in families are often associated with low vitamin D
• Health problems can persist through many generations – Epigenetics and Vitamin D

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 - 120 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.

+4) Back Pain

   probably want at least 2 clues before taking adding vitamin D, Omega-3, Magnesium, Resveratrol, etc
