The combined impact of metabolic gene polymorphisms on elite endurance athlete status and related phenotypes
AssociationN=2,555Ildus I. Ahmetov et al.(2009)· Human Genetics

This case-control study of 1,423 Russian athletes and 1,132 controls examined 15 metabolic gene polymorphisms associated with elite endurance athlete status. Ten 'endurance alleles' were identified: rs4253778 (PPARA), rs2016520 (PPARD), rs8192678 (PPARGC1A), rs7732671 (PPARGC1B), rs1937 (TFAM), rs660339 (UCP2), rs1800849 (UCP3), rs2010963 (VEGFA), NFATC4 rs2229309, and PPP3R1 promoter 5I. The proportion of subjects with ≥9 endurance alleles was significantly higher in elite endurance athletes versus controls (85.7% vs 37.8%, P=7.6×10⁻⁶). The number of endurance alleles positively correlated with slow-twitch muscle fiber proportion (r=0.50, P=4.0×10⁻⁴) and maximal oxygen consumption (r=0.46, P=7.0×10⁻⁴).

The –786C/T single‐nucleotide polymorphism in the promoter of the gene for endothelial nitric oxide synthase: Insensitivity to physiologic stimuli as a risk factor for rheumatoid arthritis
AssociationN=219Inga Melchers et al.(2006)· Arthritis & Rheumatism

This journal issue contains multiple genetic association studies on rheumatoid arthritis (RA). A key REMARCA study (146 aCCP+ RA patients vs 314 controls) identified polymorphisms in CTLA4 (rs231775 +49A/G), IL10 (rs1800872 -592A/C), and IL6R (rs8192284 +358A/C) associated with high inflammatory disease activity, with CTLA4 and IL10 minor alleles showing increased risk (OR=1.4, p=0.02 and OR=1.9, p<0.0001 respectively) and IL6R minor allele being protective (OR=0.7, p=0.03). A separate study analyzed NOS3, PPARG, PPARGC1A, PPARGC1B and PAI1 polymorphisms in 73 RA patients for cardiovascular risk.

About PPARGC1B

The protein encoded by this gene stimulates the activity of several transcription factors and nuclear receptors, including estrogen receptor alpha, nuclear respiratory factor 1, and glucocorticoid receptor. The encoded protein may be involved in fat oxidation, non-oxidative glucose metabolism, and the regulation of energy expenditure. This protein is downregulated in prediabetic and type 2 diabetes mellitus patients. Certain allelic variations in this gene increase the risk of the development of obesity. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]
