Strength of the evidence

There is no record yet to score this position by (a ClinVar disease classification or a genome-wide significant study). That is not the same as weak evidence.

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 Conflicting classifications of pathogenicity for Facial dysmorphism, hypertrichosis, epilepsy, intellectual/developmental delay, and gingival overgrowth syndrome; criteria provided, conflicting classifications (1 of 4 stars, 2 submitters), last evaluated 2025-05-21. ClinVar record 1354165 NM_033310.3(KCNK4):c.760G>A (p.Gly254Arg)

Classification Uncertain significance; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2022-07-31. ClinVar record 2428906 NM_033310.3(KCNK4):c.760G>C (p.Gly254Arg)

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 Facial dysmorphism, hypertrichosis, epilepsy, intellectual/developmental delay, and gingival overgrowth 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 VCV001354165, criteria provided, conflicting classifications)
A/G One copy of the version labs disagree about for Facial dysmorphism, hypertrichosis, epilepsy, intellectual/developmental delay, and gingival overgrowth 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 VCV001354165, criteria provided, conflicting classifications)
G/G No copy of the version labs disagree about for Facial dysmorphism, hypertrichosis, epilepsy, intellectual/developmental delay, and gingival overgrowth syndrome: in ClinVar, some labs call it disease-causing and others do not. This is the usual result. (ClinVar VCV001354165, criteria provided, conflicting classifications)

Questions about rs777868070

What is rs777868070?

rs777868070 is a single position in the genome, in or near the KCNK4 gene. Published research associates it with facial dysmorphism, hypertrichosis, epilepsy, intellectual/developmental delay, and gingival overgrowth 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 rs777868070 linked to?

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

Does having rs777868070 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 rs777868070 come from?

ClinVar VCV001354165, 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.
