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.

What ClinVar records

Classification Likely pathogenic for Monogenic diabetes; reviewed by expert panel (3 of 4 stars, 1 submitter), last evaluated 2023-07-30. ClinVar record 2574173 NM_175914.5(HNF4A):c.901A>T (p.Ile301Phe)

Classification Uncertain significance/Uncertain risk allele for Monogenic diabetes, Maturity-onset diabetes of the young; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 2 submitters), last evaluated 2017-10-13. ClinVar record 917410 NM_175914.5(HNF4A):c.901A>G (p.Ile301Val)

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 No copy of the version ClinVar lists as likely disease-causing for Monogenic diabetes. This is the usual result. (ClinVar VCV002574173, reviewed by expert panel)
A/T One copy of the version ClinVar lists as likely disease-causing for Monogenic diabetes. 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. (ClinVar VCV002574173, reviewed by expert panel)
T/T Two copies of the version ClinVar lists as likely disease-causing for Monogenic diabetes. 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 VCV002574173, reviewed by expert panel)

Questions about rs920346355

What is rs920346355?

rs920346355 is a single position in the genome, in or near the HNF4A gene. Published research associates it with monogenic diabetes. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs920346355 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 rs920346355 come from?

ClinVar VCV002574173, reviewed by expert panel. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
