LINC02240, variants, traits, and what the research shows

LINC02240 - what this gene does

LINC02240 (long intergenic non-coding RNA 02240) is a non-coding RNA gene - meaning it produces RNA transcripts but no protein - with variants linked in population-level genetic research to pharmacogenomics (how individuals respond to drugs), kidney function, respiratory traits, liver-related traits, and cancer. The gene's precise biological mechanism is not characterized in the current dataset; the description here is grounded entirely in the trait associations observed across its variants.

Key takeaways

• Variants near this gene have been associated with five broad trait categories: drug response, kidney function, respiratory health, liver-related traits, and cancer.
• The highest-magnitude signals include pharmacogenomics and kidney associations, each at the top score in the dataset.
• Two separate respiratory-trait variants and two separate cancer-trait variants have been identified, lending modest convergent support to those signals.
• Lower-magnitude variants also connect to metabolic and neurological traits.
• All associations are population-level statistical findings from genome-wide association studies and are not predictions for any individual.

Notable variants

The strongest associations cluster at magnitude 4.50. rs114983361 is linked to pharmacogenomics traits, and rs12186945 is associated with kidney-related phenotypes - both carry published reference pages. Respiratory associations appear across two independent variants, rs12520745 and rs17152484, providing some convergent support for a respiratory signal at this locus. A liver-related trait is tagged by rs62374660. Cancer associations are carried by both rs6862844 and rs77748548, each at the same top magnitude tier. Additional high-magnitude variants - rs140843945, rs149998495, rs375226983, rs62374694, and rs6880658 - are on file but lack trait annotations in the current dataset.

Trait associations

Across 95 variants in the current dataset, the documented trait themes span pharmacogenomics, kidney function, respiratory health, liver-related traits, metabolic traits, neurological traits, and cancer. Pharmacogenomics is tagged by rs114983361. Kidney function associations center on rs12186945. Respiratory traits are independently linked to both rs12520745 and rs17152484, with both at the same magnitude tier - the presence of two independent signals modestly strengthens the respiratory association in this region. Liver-related traits are represented by rs62374660. Two distinct cancer-associated variants - rs6862844 and rs77748548 - appear at the highest magnitude level, similarly echoing a potential cancer-relevant signal. At lower magnitudes, metabolic trait associations are noted for rs10057590 and rs10078386, and a neurological trait association is recorded for rs10060023.

Evidence quality

The strongest signals come from variants scored at magnitude 4.50, including pharmacogenomics and kidney associations that have published reference pages. The presence of two independent respiratory-trait and two independent cancer-trait variants at the same magnitude tier provides modest convergent support, but this internal pattern does not substitute for multi-cohort external replication. Detailed study-level metadata - such as sample sizes, odds ratios, and cohort validation status - is not available in the current dataset for most variants. Lower-magnitude variants (2.20 to 2.80) carry weaker or less-replicated signals and should be treated as preliminary. Independent large-cohort replication is needed before any association in this gene can be considered established.

What this is NOT

These variants are population-level statistical signals identified in genome-wide association studies and are not deterministic predictors of any individual outcome. Nothing on this page constitutes medical advice, a clinical diagnosis, or a recommendation of any kind.
