Gout is associated with dyslipidaemia. Association of the apolipoprotein A1-C3-A4 gene cluster with gout has previously been reported in a small study. To investigate a possible causal role for this locus in gout, we tested the association of genetic variants fromAPOA1(rs670) andAPOC3(rs5128) with gout.
We studied data for 2452 controls and 2690 clinically ascertained gout cases of European and New Zealand Polynesian (Māori and Pacific) ancestry. Data were also used from the publicly available Atherosclerosis Risk in Communities study (n = 5367) and the Framingham Heart Study (n = 2984). Multivariate adjusted logistic and linear regression was used to test the association of single-nucleotide polymorphisms with gout risk, serum urate, triglyceride and high-density lipoprotein cholesterol (HDL-C).
In Polynesians, the T-allele ofrs670(APOA1) increased (odds ratio, OR = 1.53, P = 4.9 × 10(-6)) and the G-allele ofrs5128(APOC3) decreased the risk of gout (OR = 0.86, P = 0.026). In Europeans, there was a strong trend to a risk effect of the T-allele forrs670(OR = 1.11, P = 0.055), with a significant protective effect of the G-allele forrs5128being observed after adjustment for triglycerides and HDL-C (OR = 0.81, P = 0.039). The effect atrs5128was specific to males in both Europeans and Polynesians. Association in Polynesians was independent of any effect ofrs670andrs5128on triglyceride and HDL-C levels. There was no evidence for association of either single-nucleotide polymorphism with serum urate levels (P ⩾ 0.10).
Our data, replicating a previous study, supports the hypothesis that the apolipoprotein A1-C3-A4 gene cluster plays a causal role in gout.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 December 2019.
All research outputs
#7,492,173
of 22,901,818 outputs
Outputs from Rheumatology
#2,876
of 6,240 outputs
Outputs of similar age
#107,109
of 299,136 outputs
Outputs of similar age from Rheumatology
#37
of 83 outputs
Altmetric has tracked 22,901,818 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,240 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.5. This one is in the 40th percentile – i.e., 40% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 299,136 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 55% of its contemporaries.
We're also able to compare this research output to 83 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 50% of its contemporaries.
