rs55799208 a variant in the CXCR2 gene

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 rs55799208 is the catalogue number of one of them, in the CXCR2 gene. Which letters you carry there — one copy from each parent — is your genotype.

CXCR2 (C-X-C motif chemokine receptor 2): The protein encoded by this gene is a member of the G-protein-coupled receptor family. This protein is a receptor for interleukin 8 (IL8). It binds to IL8 with high affinity, and transduces the signal through a G-protein activated second messenger system.

Why might it matter?

ClinVar records this variant as conflicting interpretations, meaning laboratories that have assessed it do not agree on whether it matters. 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

• CXCR2-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?

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?

1. Find out whether you carry it. Reading about a variant says nothing about you until you know your genotype.
2. Put it in context. Add your blood results, so the variant can be read against what your body is doing.
3. Ask questions. Dr. Hemsworth, our AI assistant, can explain this variant and your results in plain English.
4. Take anything that worries you to a professional. A GP or genetic counsellor can order a confirmatory test and interpret it with your history.
