KIF5A · rs775249

What the study found

Who was studied 3,200 European ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.212 higher (95% confidence interval 0.16-0.26); p = 4 × 10−16.

How common The C allele had a frequency of about 66% in the people studied.

Where it sits Chromosome 12, band 12q13.3 — inside KIF5A.

What ClinVar records

Classification Benign for Hereditary spastic paraplegia 10, Spastic paraplegia, Hereditary spastic paraplegia; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 5 submitters), last evaluated 2026-01-12. ClinVar record 309953 NM_004984.4(KIF5A):c.36+5C>T

What this is ClinVar's aggregate record for this position (as of its 2026-10-12 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

C/C Two copies of the version the research linked to Blood protein levels. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/T One copy of the version the research linked to Blood protein levels. That is a smaller link than two copies.
T/T No copy of the version the research linked to Blood protein levels. This is the starting point the study compared everyone against.

Questions about rs775249

What is rs775249?

rs775249 is a single position in the genome, in or near the KIF5A gene. Published research associates it with blood protein levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs775249 mean I will get this?

No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.

Where does the information about rs775249 come from?

GWAS Catalog, Science (New York, N.Y.) 2018, PMID:30072576. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
