What the study found

Who was studied 8,541 African American individuals, 3,485 Hispanic American individuals, 16,124 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 7.2 (z-score) higher (95% confidence interval -); p = 6 × 10−13.

How common The A allele had a frequency of about 15% in the people studied.

Where it sits Chromosome 4, band 4q13.3 — between genes, 74 kb from GC.

What each result means

A/A Two 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.
A/G One copy of the version the research linked to Serum 25-Hydroxyvitamin D levels. That is a smaller link than two copies.
G/G No 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 rs17767445

What is rs17767445?

rs17767445 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 rs17767445 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 rs17767445 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 rs17767445 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.
