Appendicular lean mass

INSR · rs1864193

What the study found

Who was studied 450,243 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0226 lower (95% confidence interval 0.017-0.028); p = 5 × 10−16.

How common The A allele had a frequency of about 14% in the people studied.

Where it sits Chromosome 19, band 19p13.2 — in the 3′ untranslated region of INSR.

What ClinVar records

Classification Benign for Insulin-resistant diabetes mellitus AND acanthosis nigricans, Leprechaunism syndrome, Rabson-Mendenhall syndrome; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 2 submitters), last evaluated 2018-01-13. ClinVar record 330376 NM_000208.4(INSR):c.*2854G>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

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

Questions about rs1864193

What is rs1864193?

rs1864193 is a single position in the genome, in or near the INSR gene. Published research associates it with appendicular lean mass. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs1864193 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 rs1864193 come from?

GWAS Catalog, Communications biology 2020, PMID:33097823. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
