Where this position leads

Condition: Joubert Syndrome

rs1555902866 Condition: Joubert Syndrome Joubert Syndrome Condition rs1555902866 rs1555902866 OFD1

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 Joubert syndrome, Orofaciodigital syndrome I; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2017-09-03. ClinVar record 532264 NM_003611.3(OFD1):c.748G>T (p.Glu250Ter)

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

G/G No copy of the version ClinVar lists as disease-causing for Joubert syndrome. This is the usual result. So far only one lab has made this call, so it may change. (ClinVar VCV000532264, criteria provided, single submitter)
G/T One copy of the version ClinVar lists as disease-causing for Joubert syndrome. 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 VCV000532264, criteria provided, single submitter)
T/T Two copies of the version ClinVar lists as disease-causing for Joubert syndrome. 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 VCV000532264, criteria provided, single submitter)

Questions about rs1555902866

What is rs1555902866?

rs1555902866 is a single position in the genome, in or near the OFD1 gene. Published research associates it with joubert syndrome. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs1555902866 linked to?

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

Does having rs1555902866 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 rs1555902866 come from?

ClinVar VCV000532264, 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.
