MAML3 · rs1531070
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.
Strength of the evidence
Its strongest genetic-study result is p = 10−11, with 1 associations in the GWAS Catalog.
4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.
What the study found
Who was studied 945 Han Chinese ancestry cases, 1,246 Han Chinese ancestry controls; replicated in 2,160 Han Chinese ancestry cases, 3,866 Han Chinese ancestry controls.
The effect Each copy of the A allele carried 1.40 times the odds of Congenital heart malformation (95% confidence interval 1.27-1.54); p = 5 × 10−12.
How common The A allele had a frequency of about 11% in the people studied.
Where it sits Chromosome 4, band 4q31.1 — in an intron of MAML3.

rs1531070 is a single position in the genome, in or near the MAML3 gene. Published research associates it with congenital heart malformation. 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.
