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 Uncertain significance; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2019-08-26. ClinVar record 928718 NM_001267550.2(TTN):c.2219G>A (p.Arg740His)

Classification Pathogenic for Hypertrophic cardiomyopathy 9; no assertion criteria provided (0 of 4 stars, 1 submitter), last evaluated 1999-08-27. ClinVar record 12649 NM_001267550.2(TTN):c.2219G>T (p.Arg740Leu)

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 ClinVar lists as disease-causing for Hypertrophic cardiomyopathy 9. 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. This call was sent to ClinVar without the lab's criteria, the least certain kind of record, so it may change. (ClinVar VCV000012649, no assertion criteria provided)
A/C One copy of the version ClinVar lists as disease-causing for Hypertrophic cardiomyopathy 9. 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. This call was sent to ClinVar without the lab's criteria, the least certain kind of record, so it may change. (ClinVar VCV000012649, no assertion criteria provided)
C/C No copy of the version ClinVar lists as disease-causing for Hypertrophic cardiomyopathy 9. This is the usual result. This call was sent to ClinVar without the lab's criteria, the least certain kind of record, so it may change. (ClinVar VCV000012649, no assertion criteria provided)

Questions about rs28933405

What is rs28933405?

rs28933405 is a single position in the genome, in or near the TTN gene. Published research associates it with hypertrophic cardiomyopathy 9. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs28933405 linked to?

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

Does having rs28933405 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 rs28933405 come from?

ClinVar VCV000012649, no assertion criteria provided. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
