Genetic variant
rs199612746 a variant in the ATP11C gene
rs199612746 is a single-letter difference in the ATP11C gene, on chromosome X. 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 ATP11C-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 rs199612746 is the catalogue number of one of them, in the ATP11C gene. Which letters you carry there — one copy from each parent — is your genotype.
ATP11C (ATPase phospholipid transporting 11C (ATP11C blood group)): Enables phosphatidylethanolamine flippase activity and phosphatidylserine flippase activity. Involved in phospholipid translocation. Located in endoplasmic reticulum and plasma membrane. Part of phospholipid-translocating ATPase complex. Implicated in X-linked congenital hemolytic anemia.

Gene description from NCBI Gene
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
- ATP11C-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 rs199612746, 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.
