Genetic variant
rs34637584 a variant in the LRRK2 gene
rs34637584 is a single-letter difference in the LRRK2 gene, on chromosome 12. ClinVar, the public archive of variant interpretations, lists it as likely pathogenic: probably able to cause or contribute to disease. It has been reported in connection with Autosomal dominant Parkinson disease 8 and Inborn genetic diseases, among others. Carrying it does not, on its own, mean you have or will develop any condition.
What is this?
Your DNA is a long sequence of four letters. At a few million positions, people commonly differ by a single letter; each of those positions is called a SNP (“snip”), and rs34637584 is the catalogue number of one of them, in the LRRK2 gene. Which letters you carry there — one copy from each parent — is your genotype.
LRRK2 (leucine rich repeat kinase 2): This gene is a member of the leucine-rich repeat kinase family and encodes a protein with an ankryin repeat region, a leucine-rich repeat (LRR) domain, a kinase domain, a DFG-like motif, a RAS domain, a GTPase domain, a MLK-like domain, and a WD40 domain. The protein is present largely in the cytoplasm but also associates with the mitochondrial outer membrane.

Why might it matter?
ClinVar records this variant as likely pathogenic, meaning probably able to cause or contribute to disease. A classification describes the variant, not you: what it means for one person depends on their genotype, their family history and often on other genes and circumstances.
Conditions it has been reported with
- Autosomal dominant Parkinson disease 8
- Inborn genetic diseases
- Young-onset Parkinson disease
- Parkinson disease, late-onset
- LRRK2-related disorder
Listed in ClinVar submissions for this variant. Being listed is a report of an association, not a statement that the variant causes the condition in any given person.
Do I have this variant?
If you have taken a consumer DNA test (23andMe, AncestryDNA and similar), you can download its raw data file and check. Create a free account, upload the file, and this page will show the letters you carry at rs34637584, if your test read this position.
Connect this with your blood results
A gene is a fixed instruction; a blood test shows what your body is doing now. CheckMyBloods reads the two side by side, so a variant can be set against the markers it could plausibly affect.
Blood markers do not diagnose a genetic condition, and a variant does not explain a blood result on its own. Together, with symptoms and family history, they give a clinician context.
What should I do next?
- Find out whether you carry it. Reading about a variant says nothing about you until you know your genotype.
- Put it in context. Add your blood results, so the variant can be read against what your body is doing.
- Ask questions. Dr. Hemsworth, our AI assistant, can explain this variant and your results in plain English.
- Take anything that worries you to a professional. A GP or genetic counsellor can order a confirmatory test and interpret it with your history.
