What the study found

Who was studied 252,730 European ancestry, African ancestry, Hispanic or Latin American, South East Asian ancestry, South Asian ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.036 higher (95% confidence interval 0.024-0.048); p = 2 × 10−9.

How common The T allele had a frequency of about 8% in the people studied.

Where it sits Chromosome 17, band 17p12 — in the 3′ untranslated region of PMP22.

What ClinVar records

Classification Benign/Likely benign; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 2 submitters), last evaluated 2018-06-14. ClinVar record 321855 NM_000304.4(PMP22):c.*228G>A

What this is ClinVar's aggregate record for this position (as of its 2026-10-12 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

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

Questions about rs1804193

What is rs1804193?

rs1804193 is a single position in the genome, in or near the PMP22 gene. Published research associates it with qt interval. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs1804193 linked to?

On MyGeneLog this position is linked to QT Interval and Drug-Induced Long QT. The research behind each link, and its sources, are set out on that condition page.

Does having rs1804193 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 rs1804193 come from?

GWAS Catalog, Nature communications 2022, PMID:36050321. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
