Title: Genetics, Genomics and Proteomics Poster

Session Type: Poster Session C

Session Time: 1:00PM-3:00PM

Background/Purpose: Alcohol consumption is a risk factor for hyperuricaemia and gout. Multiple single nucleotide polymorphisms (SNPs) have been identified as associated with both habitual alcohol consumption and serum urate levels or gout in separate genome-wide association studies (GWASs). The aim of this study was to systematically identify and characterize interactions between these shared SNPs and alcohol consumption for association with hyperuricaemia and gout.

Methods: This research was conducted using cross-sectional data from the UK Biobank. The association of alcohol consumption (units per week) with serum urate levels and gout was tested among more than 340,000 individuals of European ethnicity. Candidate SNPs for interaction analysis were identified by comparing serum urate, gout, and alcohol consumption GWASs for overlap and selecting the lead shared urate or gout-associated SNP at each locus. Multivariable-adjusted linear and logistic regression analyses were conducted with the inclusion of an interaction term to identify SNP-alcohol consumption interactions for hyperuricaemia and gout. The nature of these interactions was characterized using genotype-stratified association analysis.

Results: Alcohol consumption was associated with elevated serum urate levels (β 0.49, SE 0.01, P < 1.0 x 10-300) and gout (OR 1.013, 95% CI 1.013-1.014, P = 1.2 x 10-173). For hyperuricaemia, interactions were identified between alcohol consumption and LOC100507053 rs11733695 (P = 1.4 x 10-3), ADH1B rs1229984 (P = 7.9 x 10-13), and ADH1C rs141973904 (P = 5.1 x 10-6). ADH1B rs1229984 additionally demonstrated interaction with alcohol consumption for association with gout (P = 8.2 x 10-9). In the genotype-stratified association analysis, presence of the T allele at ADH1B rs1229984 was not associated with hyperuricaemia or gout in non-drinkers (Table 1). However, in the alcohol-exposed subgroup, the T-positive genotype was associated with increased hyperuricaemia and gout compared to the T-negative genotype. Similarly, LOC100507053 rs11733695 and ADH1C rs141973904 were only associated with hyperuricaemia among drinkers and not non-drinkers.

Conclusion: In this large study of European participants, novel interactions with alcohol consumption for hyperuricaemia or gout were identified at LOC100507053, ADH1B, and ADH1C. This may represent a single signal at ADH1B rs1229984 with linkage disequilibrium explaining the other two significant interactions. The association of ADH1B with serum urate levels and gout may occur through the modulation of alcohol metabolism rate among drinkers.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
