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

4 / 4

ClinVar classifies it as disease-causing (or likely), reviewed at 3 of 4 stars.

How this is scored

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.

Change history MyGeneLog™ keeps a copy of every weekly release from 2026-10-19 and compares them. This position's classification has not changed since.

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 Two copies of the version labs disagree about for Hereditary cancer-predisposing syndrome: in ClinVar, some labs call it disease-causing and others do not. A result like this should be confirmed by a medical genetic test and talked through with a doctor; consumer DNA files can misread rare variants. (ClinVar VCV000185822, criteria provided, conflicting classifications)
A/T One copy of the version labs disagree about for Hereditary cancer-predisposing syndrome: in ClinVar, some labs call it disease-causing and others do not, so what one copy means is not settled. A genetic counsellor can look at the separate records. (ClinVar VCV000185822, criteria provided, conflicting classifications)
T/T No copy of the version labs disagree about for Hereditary cancer-predisposing syndrome: in ClinVar, some labs call it disease-causing and others do not. This is the usual result. (ClinVar VCV000185822, criteria provided, conflicting classifications)

Questions about rs786201838

What is rs786201838?

rs786201838 is a single position in the genome, in or near the TP53 gene. Published research associates it with hereditary cancer-predisposing syndrome. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs786201838 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 rs786201838 come from?

ClinVar VCV000185822, criteria provided, conflicting classifications. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
