Where this position leads

What the study found

Who was studied 374,756 European ancestry male individuals.

The effect Each copy of the A allele shifted the measure 0.0119 lower (95% confidence interval 0.0088-0.015); p = 2 × 10⁻¹³.

How common The A allele had a frequency of about 54% in the people studied.

Where it sits Chromosome 2, band 2q35 — in an intron of TTLL4.

What each result means

A/A Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Body mass index compared to the general population.

A/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Body mass index.

G/G Published research associates this genotype with typical/baseline likelihood of Body mass index — no copies of the reported risk allele.

Questions about rs1541777

What is rs1541777?

rs1541777 is a single position in the genome, in or near the TTLL4 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 rs1541777 linked to?

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

Does having rs1541777 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 rs1541777 come from?

GWAS Catalog, Hum Mol Genet 2018, PMID:30239722. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
