What the study found

Who was studied 1,122,049 European ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.0182 lower (95% confidence interval 0.012-0.024); p = 6 × 10−9.

Where it sits Chromosome 5, band 5q13.2 — a missense change in MAP1B.

What ClinVar records

Classification Benign for Periventricular nodular heterotopia 9; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2023-05-04. ClinVar record 3068588 NM_005909.5(MAP1B):c.5749A>C (p.Ser1917Arg)

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.

What each result means

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

Questions about rs13153166

What is rs13153166?

rs13153166 is a single position in the genome, in or near the MAP1B gene. Published research associates it with body mass index. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs13153166 linked to?

On MyGeneLog this position is linked to Childhood Body Mass Index, Obesity and Body Weight. The research behind each link, and its sources, are set out on that condition page.

Does having rs13153166 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 rs13153166 come from?

GWAS Catalog, Nature communications 2022, PMID:36581621. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
