Genetic variant
rs3088362 a variant in the CCDC122 gene
rs3088362 is a single-letter difference in the CCDC122 gene, on chromosome 13. ClinVar, the public archive of variant interpretations, lists it as uncertain significance: not yet understood well enough to say whether it matters. It has been reported in connection with Leprosy, susceptibility to and 1. 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 rs3088362 is the catalogue number of one of them, in the CCDC122 gene. Which letters you carry there — one copy from each parent — is your genotype.
CCDC122 (coiled-coil domain containing 122): This gene encodes a protein that contains a coiled-coil domain. Naturally occurring mutations in this gene are associated with leprosy. [provided by RefSeq, Apr 2017]

Why might it matter?
ClinVar records this variant as uncertain significance, meaning not yet understood well enough to say 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
- Leprosy, susceptibility to
- 1
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 rs3088362, 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.
