Using these rheumatic diseases as an example of proof of concept, our aim was to develop a tool that simplifies analysis of gene\u2013disease associations applicable to any disease and to perform comparisons. This tool is meant to provide insights into associated gene symbols and gene expression data to identify candidate biomarkers in common among these diseases. The Diseasesv2.0 and GTExv8 databases were utilized for data collection, providing searchable disease names, affiliated gene symbols, confidence scores (ranging from 0 to 5, with 5 being the most confident), and gene expression across the panel of 54 tissue types present in GTExv8. Data infrastructure was established on a Postgres database using Plotlyv5.17.0 and Streamlitv1.27.2 Python packages. The resulting database was used to investigate the genetic associations among SjD, RA, and SLE, including confidence scores from 2.50 to 5.00. STRINGv12 analysis determined significant pathways (FDR &lt; 0.05). Analysis using our tool revealed the following refined gene associations for each disease: SjD based on \u2018Sjogren\u2019 search term (n = 12 genes), RA (n = 231 genes), and SLE (n = 137 genes). We found seven genes in common, namely, CD4, CD8A, IL6, IL17A, TNFS13B, TNF, and TRIM21. With the exception of IL17A, these genes were expressed in tissue types known or suggested to be affected by SjD. STRINGv12 determined significant KEGG pathways involving interleukin signaling, cytokine signaling, and the immune system. We developed a tool that simplifies the data mining process, allowing users to search for diseases of interest and view common gene associations and gene expression. Some of the genes identified through our tool may be further explored to better understand SjD pathogenesis and systemic impact.<\/jats:p>","DOI":"10.3390\/ijms26136379","type":"journal-article","created":{"date-parts":[[2025,7,2]],"date-time":"2025-07-02T09:08:44Z","timestamp":1751447324000},"page":"6379","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["GeneHarmony: A Knowledge-Based Tool for Biomarker Discovery in Disease: Sj\u00f6gren\u2019s Disease vs. Rheumatoid Arthritis and Systemic Lupus Erythematosus"],"prefix":"10.3390","volume":"26","author":[{"given":"Micaela F.","family":"Beckman","sequence":"first","affiliation":[{"name":"Translational Research Laboratories, Department of Oral Medicine\/Oral & Maxillofacial Surgery and Cannon Research Center, Atrium Health Carolinas Medical Center, Charlotte, NC 28203, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-8801-9888","authenticated-orcid":false,"given":"Adam","family":"Alexander","sequence":"additional","affiliation":[{"name":"Translational Research Laboratories, Department of Oral Medicine\/Oral & Maxillofacial Surgery and Cannon Research Center, Atrium Health Carolinas Medical Center, Charlotte, NC 28203, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8953-1769","authenticated-orcid":false,"given":"Jean-Luc C.","family":"Mougeot","sequence":"additional","affiliation":[{"name":"Translational Research Laboratories, Department of Oral Medicine\/Oral & Maxillofacial Surgery and Cannon Research Center, Atrium Health Carolinas Medical Center, Charlotte, NC 28203, USA"},{"name":"Otolaryngology\/Head and Neck Surgery, Wake Forest University School of Medicine, Winston-Salem, NC 27110, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8903-333X","authenticated-orcid":false,"given":"Farah","family":"Bahrani Mougeot","sequence":"additional","affiliation":[{"name":"Translational Research Laboratories, Department of Oral Medicine\/Oral & Maxillofacial Surgery and Cannon Research Center, Atrium Health Carolinas Medical Center, Charlotte, NC 28203, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"369","DOI":"10.1111\/joim.12395","article-title":"Human autoimmune diseases: A comprehensive update","volume":"278","author":"Wang","year":"2015","journal-title":"J.
