rs40270 C5orf67
A allele associated with increased Sex hormone-binding globulin levels adjusted for BMI (β=0.016). [GWAS Catalog]
What is rs40270?
rs40270 is a single-nucleotide polymorphism (SNP) in the C5orf67 gene. Each person carries two copies, one from each parent, so a result is reported as a pair of letters such as AA. The table below describes what studies associate with each genotype; the association is statistical, across populations, and is not a diagnosis.
What does each rs40270 genotype mean?
| Genotype | Association | What the evidence says | Confidence |
|---|---|---|---|
| AA | increased | A allele associated with increased Sex hormone-binding globulin levels adjusted for BMI (β=0.016). [GWAS Catalog] | 90% |
| CC | typical | C allele associated with increased Triglyceride levels (UKB data field 30870) (β=0.033). [GWAS Catalog] | 85% |
Is rs40270 on 23andMe and AncestryDNA chips?
Chip coverage is not recorded for this variant. Orviva reports it when a raw-data file contains it directly or via a well-correlated proxy SNP, and says so when it does not.

Genetic associations describe risk across populations, not a diagnosis for any one person. Most variants shift risk modestly and act alongside lifestyle, environment and other genes. Consumer DNA chips do not read every position and can be wrong at any single one. For general education only; talk to a clinician or genetic counsellor before acting on anything here, and never change a prescribed medicine without your prescriber.
