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 Likely pathogenic for Fabry disease; criteria provided, single submitter (1 of 4 stars, 1 submitter). ClinVar record 2687480 NM_000169.3(GLA):c.116C>G (p.Thr39Arg)

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 Two copies of the version ClinVar lists as likely disease-causing for Fabry disease. 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 VCV002687480, criteria provided, single submitter)
C/G One copy of the version ClinVar lists as likely disease-causing for Fabry disease. 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 VCV002687480, criteria provided, single submitter)
G/G No copy of the version ClinVar lists as likely disease-causing for Fabry disease. This is the usual result. So far only one lab has made this call, so it may change. (ClinVar VCV002687480, criteria provided, single submitter)

Questions about rs201819574

What is rs201819574?

rs201819574 is a single position in the genome, in or near the GLA gene. Published research associates it with fabry disease. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs201819574 linked to?

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

Does rs201819574 affect how medicines work?

GLA carries pharmacogenomic findings for Migalastat (Galafold). That is educational information, not a prescription or a dosing guide. Any decision to start, stop or change a medicine belongs with the clinician or pharmacist managing your treatment.

Does having rs201819574 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 rs201819574 come from?

ClinVar VCV002687480, 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.
