Genetic variant

rs203462 a variant in the AKAP10 gene

rs203462 is a single-letter difference in the AKAP10 gene, on chromosome 17. ClinVar, the public archive of variant interpretations, lists it as conflicting interpretations: laboratories that have assessed it do not agree on whether it matters. It has been reported in connection with Reclassified - variant of unknown significance and AKAP10-related disorder. 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 rs203462 is the catalogue number of one of them, in the AKAP10 gene. Which letters you carry there — one copy from each parent — is your genotype.

AKAP10 (A-kinase anchoring protein 10): This gene encodes a member of the A-kinase anchor protein family. A-kinase anchor proteins bind to the regulatory subunits of protein kinase A (PKA) and confine the holoenzyme to discrete locations within the cell. The encoded protein is localized to mitochondria and interacts with both the type I and type II regulatory subunits of PKA.

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

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 rs203462, 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?

  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.
