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.
rs3796621 is a single position in the genome, in or near the IDUA gene. Published research associates it with phospholipids to total lipids in large vldl percentage. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Cholesterol (LDL, HDL and Total). The research behind each link, and its sources, are set out on that condition page.
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.
