research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 321,047 European ancestry individuals; replicated in 24,218 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.0177 higher (95% confidence interval 0.012-0.024); p = 2 × 10−9.
How common The T allele had a frequency of about 24% in the people studied.
Where it sits Chromosome 22, band 22q11.21 — in an intron of MICAL3.
What each result means
C/C
Published research associates this genotype with typical/baseline likelihood of Peak expiratory flow — no copies of the reported risk allele.
C/T
Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Peak expiratory flow.
T/T
Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Peak expiratory flow compared to the general population.

Questions about rs1978968
What is rs1978968?
rs1978968 is a single position in the genome, in or near the MICAL3 gene. Published research associates it with peak expiratory flow. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs1978968 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 rs1978968 come from?
GWAS Catalog, Nat Genet 2019, PMID:30804560. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
