CAST · rs17085675
Stands on its own. Nothing else here links to this position yet — but the page above is the point: what the research found, what each genotype means, and where it came from, in language you can read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 12,224 European ancestry cases, 288,329 European ancestry controls.
The effect Each copy of the A allele carried 1.14 times the odds of ICD10 O24.4: Diabetes mellitus arising in pregnancy (95% confidence interval 1.11-1.18); p = 6 × 10−19.
Where it sits Chromosome 5, band 5q15 — in the 3′ untranslated region of CAST.

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
rs17085675 is a single position in the genome, in or near the CAST gene. Published research associates it with icd10 o24.4: diabetes mellitus arising in pregnancy. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
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.
