Where this position leads

Condition: Fanconi Anemia

rs2147404831 Condition: Fanconi Anemia Fanconi Anemia Condition rs2147404831 rs2147404831 FANCB

Strength of the evidence

2 / 4

ClinVar classifies it as disease-causing (or likely), reviewed at 1 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.

What ClinVar records

Classification Pathogenic for Fanconi anemia; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2020-11-26. ClinVar record 1391114 NM_001018113.3(FANCB):c.1437G>A (p.Trp479Ter)

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

C/C No copy of the version ClinVar lists as disease-causing for Fanconi anemia. This is the usual result. So far only one lab has made this call, so it may change. (ClinVar VCV001391114, criteria provided, single submitter)
C/T One copy of the version ClinVar lists as disease-causing for Fanconi anemia. Some conditions need only one copy; for others, one copy makes a person a carrier who is usually healthy but can pass it on. A genetic counsellor can say which applies. So far only one lab has made this call, so it may change. (ClinVar VCV001391114, criteria provided, single submitter)
T/T Two copies of the version ClinVar lists as disease-causing for Fanconi anemia. 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. So far only one lab has made this call, so it may change. (ClinVar VCV001391114, criteria provided, single submitter)

Questions about rs2147404831

What is rs2147404831?

rs2147404831 is a single position in the genome, in or near the FANCB gene. Published research associates it with fanconi anemia. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs2147404831 linked to?

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

Does having rs2147404831 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 rs2147404831 come from?

ClinVar VCV001391114, criteria provided, single submitter. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
