Who was studied 8,541 African American individuals, 3,485 Hispanic American individuals, 16,124 European ancestry individuals.
The effect
Each copy of the C allele shifted the measure 6.14 (z-score) higher (95% confidence interval -); p = 8 × 10−10.
How common The C allele had a frequency of about 33% in the people studied.
Where it sits Chromosome 4, band 4q13.3 — in an intron of NPFFR2.
What each result means
C/CTwo copies of the version the research linked to Serum 25-Hydroxyvitamin D levels. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/TOne copy of the version the research linked to Serum 25-Hydroxyvitamin D levels. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Serum 25-Hydroxyvitamin D levels. This is the starting point the study compared everyone against.

Questions about rs13107347
What is rs13107347?
rs13107347 is a single position in the genome, in or near the GC gene. Published research associates it with serum 25-hydroxyvitamin d levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs13107347 linked to?
On MyGeneLog this position is linked to Vitamin D Deficiency and the GC Gene. The research behind each link, and its sources, are set out on that condition page.
Does having rs13107347 mean I will get this?
No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.
Where does the information about rs13107347 come from?
GWAS Catalog, J Clin Endocrinol Metab 2018, PMID:29325163. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
