Composite immunoglobulin trait (IgA/IgM)

IGHA1 · rs112763553

What the study found

Who was studied 14,183 Icelandic ancestry individuals; replicated in 2,146 Swedish ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.13 SD units higher; p = 2 × 10−11.

How common The A allele had a frequency of about 15% in the people studied.

Where it sits Chromosome 14, band 14q32.33 — between genes, 0.7 kb from IGHA1.

What each result means

A/A Two copies of the version the research linked to Composite immunoglobulin trait (IgA/IgM). That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to Composite immunoglobulin trait (IgA/IgM). That is a smaller link than two copies.
G/G No copy of the version the research linked to Composite immunoglobulin trait (IgA/IgM). This is the starting point the study compared everyone against.

Questions about rs112763553

What is rs112763553?

rs112763553 is a single position in the genome, in or near the IGHA1 gene. Published research associates it with composite immunoglobulin trait (iga/igm). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs112763553 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 rs112763553 come from?

GWAS Catalog, Nature genetics 2017, PMID:28628107. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
