What the research says A metabolic genome-wide association study (mGWAS) of 490 elite athletes from diverse sport disciplines genotyped 275,016 single nucleotide polymorphisms (common single-letter DNA variants) alongside serum metabolomics profiling of 751 metabolites, seeking metabolic quantitative trait loci (mQTLs) - genetic variants that influence levels of specific metabolites in blood. The study compared mQTLs identified in this elite athlete cohort to those previously reported in non-athlete populations, with additional focus on metabolites linked to endurance sports. rs10983999, located near TPT1P9 (a pseudogene - a non-functional copy of a gene) and LINC02578 (a long intergenic non-coding RNA - a genomic sequence that is transcribed but does not produce a protein), was among the variants analyzed in this framework.

Reported associations

  • Metabolic quantitative trait locus in elite athletes: This locus was examined in a metabolic GWAS of 490 elite athletes investigating genetically-influenced serum metabolites potentially linked to athletic performance; specific metabolite associations and effect sizes for this variant are not detailed in the available study excerpt

Evidence quality The only available evidence for this locus comes from a single mGWAS of 490 elite athletes - a specialized cohort that may not represent the general population. The study applied quality control to more than 275,000 genotyped variants and corrected for gender, hemolysis levels, metabolomics principal components, and ethnicity, strengthening internal validity. However, a sample size of 490 is modest for detecting small-effect common variants, no independent replication data are present in the available evidence, and the specific p-value and effect size for this variant are not visible in the available study excerpt. Any association at this locus should be considered preliminary until confirmed in larger, independent studies.

Frequently asked questions

What is rs10983999?

rs10983999 is a common single-letter DNA variant (SNP) located near two non-protein-coding elements: TPT1P9, a pseudogene (a non-functional copy of a gene), and LINC02578, a long intergenic non-coding RNA. It was studied in a metabolic genome-wide association analysis of elite athletes.

What is LINC02578?

LINC02578 is a long intergenic non-coding RNA - a segment of genomic DNA that is copied into RNA but does not produce a protein. Such elements can play regulatory roles in gene expression, though their specific functions are often still under active investigation.

Is rs10983999 linked to athletic performance?

rs10983999 was included in a metabolic genome-wide association study of 490 elite athletes designed to identify genetic variants that influence blood metabolite levels in athletes. The evidence is preliminary and based on a single study in a specialized population.

What is a metabolic GWAS or mQTL?

A metabolic genome-wide association study (mGWAS) scans the genome for variants that influence the levels of specific metabolites - small molecules measurable in blood that reflect biological processes. A metabolic quantitative trait locus (mQTL) is a genomic location where such a variant is identified.

How reliable is the evidence for rs10983999?

Evidence for rs10983999 comes from a single study of 490 elite athletes and has not been replicated in independent cohorts based on the available data. The small and specialized sample means findings should be treated as preliminary until confirmed in larger studies.
