rs11687515 (THORLNC): Sex-specific inflammation

Key takeaways

  • rs11687515 at the THORLNC long non-coding RNA locus shows male-specific effects on circulating inflammatory protein levels in European populations.
  • Roughly 67% of all inflammatory protein pQTLs in the source study were shared between sexes, placing this variant among a rare class of sex-specific signals.
  • Cross-validation confirmed that sex-specific pQTL variants, including those at lncRNA loci, are associated with sex-specific phenotypic traits.
  • The evidence comes from a meta-analysis of two Dutch cohorts using the Olink Inflammation panel across 66 proteins and over 4 million SNPs.

Key takeaways

  • rs11687515 sits at the THORLNC locus (a long non-coding RNA, or lncRNA, meaning it produces regulatory RNA rather than protein), identified in a sex-stratified analysis of 66 inflammatory proteins in Dutch European populations.
  • This variant shows male-specific protein quantitative trait loci (pQTL) effects, meaning its influence on circulating inflammatory protein levels differs by sex.
  • Roughly 67% of all pQTL signals in the source study were shared between males and females, making this a relatively rare sex-specific regulatory signal.
  • Cross-validation confirmed that sex-specific pQTL variants are linked to sex-specific phenotypic traits, supporting the biological relevance of this male-specific signal.

What the research says A sex-stratified meta-analysis of two Dutch population-based cohorts (500FG and 300BCG, European ancestry) mapped pQTLs across 66 inflammatory proteins measured via the Olink Inflammation panel and over 4 million SNPs. Colocalization analysis identified evidence of sex-dependent modulation at this locus in males, and cross-validation confirmed that male-specific pQTL signals correlate with male-specific phenotypic traits.

Reported associations

  • Inflammatory protein levels (male-specific): This variant was identified by sex-stratified pQTL mapping as having a male-specific association with circulating inflammatory protein concentrations in two European cohorts.
  • Sex-specific phenotypic traits: Male-specific pQTL variants at lncRNA loci in this study were cross-validated as being linked to male-specific phenotypic traits.

Evidence quality The evidence comes from a meta-analysis of two European cohorts using the Olink Inflammation panel covering 66 proteins and over 4 million SNPs, with colocalization methods applied to distinguish sex-dependent from shared signals. Approximately 67% of pQTL signals were shared between sexes, confirming that sex-specific signals like this one represent a minority. Specific p-values, per-allele effect sizes, and per-cohort sample sizes for this variant are not available in the provided study text. The analysis is limited to individuals of European descent, and independent replication in non-European populations has not been reported in the available material. This places the current evidence in a preliminary category.

Frequently asked questions

What is the THORLNC gene?

THORLNC is a long non-coding RNA (lncRNA), meaning it is a genomic region that produces RNA molecules which help regulate gene activity rather than encoding protein. rs11687515 is a genetic variant located at this locus.

What is a pQTL and why does it matter?

A protein quantitative trait locus (pQTL) is a genetic variant associated with differences in the level of a specific protein circulating in the blood. Identifying pQTLs helps researchers understand how genetic variation influences immune and inflammatory processes.

Why does sex matter for rs11687515?

Research found that the effect of this variant on inflammatory protein levels appears specifically in males, not females, classifying it as a sex-specific pQTL. This type of sex-dependent signal may help explain why certain inflammatory diseases affect men and women at different rates or severities.

Which inflammatory proteins are regulated by rs11687515?

The specific proteins regulated by this variant are not identified in the available study text. The source study used the Olink Inflammation panel covering 66 inflammatory proteins, but per-protein results for this variant are not reported in the available excerpt.

Is rs11687515 linked to any specific disease?

The source study cross-validated sex-specific pQTL variants with sex-specific phenotypic traits but did not name specific diseases for this variant in the available text. The broader study context concerns inflammatory conditions that differ in prevalence or severity between males and females.
