Maturity-onset diabetes of the young type 2

GCK · rs193922305

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

C/C No copy of the version ClinVar lists as likely disease-causing for Maturity-onset diabetes of the young type 2. This is the usual result. (ClinVar VCV000036227, reviewed by expert panel)
C/T One copy of the version ClinVar lists as likely disease-causing for Maturity-onset diabetes of the young type 2. 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 VCV000036227, reviewed by expert panel)
T/T Two copies of the version ClinVar lists as likely disease-causing for Maturity-onset diabetes of the young type 2. 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 VCV000036227, reviewed by expert panel)

Questions about rs193922305

What is rs193922305?

rs193922305 is a single position in the genome, in or near the GCK gene. Published research associates it with maturity-onset diabetes of the young type 2. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs193922305 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 rs193922305 come from?

ClinVar VCV000036227, 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.
