Therefore, identification of reliable biomarkers is necessary to significantly improve the diagnostic accuracy and therapeutic outcomes of CCDs. This study analyzed GWAS summary datasets using a genomic structural equation model (Genomic\u2010SEM), fine mapping, linkage disequilibrium score regression (LDSC), and two\u2010sample Mendelian randomization (TSMR) analyses to identify genetic loci and genes associated with CCDs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>GWAS summary datasets of European subjects were obtained from the GWAS Catalog and FinnGen databases. The GenomicSEM R package was used to construct a structural equation model to identify common latent factors influencing CCD progression. The Functional Mapping and Annotation of Genome\u2010Wide Association Studies (FUMA) platform was used to annotate the lead SNPs and candidate genes. Fine\u2010mapping tools, such as SuSiE and FINEMAP, and Phenome\u2010Wide Association Study (PheWAS) analysis were used to identify causal SNPs associated with CCDs. Transcriptome\u2010Wide Association Study (TWAS) and Functional Summary Statistics (FOCUS) analyses were performed to identify CCD susceptibility genes. LDSC and TSMR were performed to determine causal relationships between the candidate risk genes and specific CCDs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Newly explored CCD\u2010associated leading SNPs (rs71208329 and rs112720315) were generated from genomic SEM and FUMA analyses.
