Genetic variant

rs1426654 a variant in the MYEF2 gene

rs1426654 is a single-letter difference in the MYEF2 gene, on chromosome 15. ClinVar, the public archive of variant interpretations, lists it as association: seen more often in people with a condition, which is not the same as causing it. It has been reported in connection with Skin/hair/eye pigmentation, variation in and 4. 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 rs1426654 is the catalogue number of one of them, in the MYEF2 gene. Which letters you carry there — one copy from each parent — is your genotype.

This SNP influences skin pigmentation. The allele, A111T, rs1426654(A), indicates light-skinned West...

Why might it matter?

ClinVar records this variant as association, meaning seen more often in people with a condition, which is not the same as causing it. 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 rs1426654, 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.
