  "abstract": "Lyme disease is a vector-borne bacterial infection with marked heterogeneity in susceptibility and clinical manifestations. We investigated the genetic architecture and clinical heterogeneity of Lyme disease using genetic and longitudinal health data from FinnGen and the Estonian Biobank. Genome-wide association analyses included 37,571 individuals with Lyme disease and 670,567 controls (N = 708,138), complemented by sex-stratified analyses and temporal phenotyping in FinnGen.\n\nThe overall GWAS meta-analysis identified three genome-wide significant loci at SCGB1D2, TLR1/TLR6, and HLA-DQA1. Sex-stratified analyses identified additional genome-wide significant signals at CPE in males ({beta} = -0.077, P = 2.99 x 10-) and the TYMP-CPT1B locus in females ({beta} = -0.064, P = 4.98 x 10-). The TLR1/6 association was more pronounced in males ({beta} = -0.141, P = 2.16 x 10-{superscript 1}{superscript 2}) than in females ({beta} = -0.060, P = 1.21 x 10-).\n\nTemporal phenotyping showed enrichment of neurological, musculoskeletal, and dermatological manifestations after Lyme disease diagnosis, with associations generally attenuating over time. Bell palsy showed the strongest association at 1-6 months (OR 11.49, P = 2.37 x 10-), while joint pain was also enriched during this interval (OR 1.74, P = 1.95 x 10-{superscript 2}3). Early associations with joint pain and Bell palsy were stronger in males than in females.\n\nThese findings expand the genetic architecture of Lyme disease, implicate innate immune sensing through the TLR1/TLR6 locus, and antigen presentation through the HLA associations. Overall, the results highlight a strong polygenic signal with Lyme disease and a connection with other post-infectious clinical manifestations.",
