Condition: Vitamin D Deficiency and the GC Gene

rs1607741 Condition: Vitamin D Deficiency and the GC Gene Vitamin D Deficiency and the GC Gene Condition rs1607741 rs1607741 near GC

What the study found

Who was studied 2,619 whole genome sequenced European ancestry individuals, up to 38,213 European ancestry individuals, 1,442 individuals.

The effect Each copy of the C allele shifted the measure 0.12 nmol/L higher (95% confidence interval 0.1-0.14); p = 1 × 10−58.

How common The C allele had a frequency of about 68% in the people studied.

Where it sits Chromosome 4, band 4q13.3 — between genes, 47.8 kb from GC.

What each result means

C/C Two copies of the version the research linked to Vitamin D levels. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/G One copy of the version the research linked to Vitamin D levels. That is a smaller link than two copies.
G/G No copy of the version the research linked to Vitamin D levels. This is the starting point the study compared everyone against.

Questions about rs1607741

What is rs1607741?

rs1607741 is a single position in the genome, in or near the near GC gene. Published research associates it with vitamin 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 rs1607741 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 rs1607741 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 rs1607741 come from?

GWAS Catalog, Am J Hum Genet 2017, PMID:28757204. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
