BA, a correctable cholangiopathy, presents with cholestatic jaundice within the first weeks of life. The inflammation of bile ducts leads to progressive fibrosclerosis involving biliary trees, followed by cirrhosis and liver failure. With the use of modern molecular studies, this research aimed to define a novel pathogenesis by exploring variations. We performed genetic discovery by using supervised and unsupervised approaches. Ultimately, a combination of genetic variations and survival data was analyzed to strengthen the novel concept in this study. In this study, coding regions were explored to identify rare deleterious variants within genes from the first analysis together with gene sets reported in PFIC, and diseases with hyperbilirubinemia. Our unsupervised prioritization was primarily designed to identify novel causal genes from nonsynonymous variants derived by three biostatistical algorithms: enrichment analysis, burden test, and trio study. Survival analysis was integratively evaluated with a combination of identified causal genes. The individuals with identified variants from the supervised approach were frequently related to the severity of cirrhosis and poor postoperative outcome. In the unsupervised approach, nonsynonymous variants were enriched. Cilium and muscle related pathways had a significant correlation.<jats:italic>CCDC8<\/jats:italic>was statistically significant gene in which six cases carried mutations identified through burden analysis. Individuals who carried variants in corresponding genes and significant pathways had significantly lower native-liver survival than individuals in whom none of these variants were identified (log-rank p value 0.016). This study explored genetic variations by multiple strategies. Different pathways of cholestatic diseases have been found to be associated with BA. Therefore, BA may be characterized as a shared sequela of many cholestatic disorders. Susceptibility in those pathways suggested an association with BA and strengthened this proposed novel hypothesis. The results emphasized the consequences of many disruptive pathophysiologies.<\/jats:p>","DOI":"10.1371\/journal.pone.0277334","type":"journal-article","created":{"date-parts":[[2022,11,9]],"date-time":"2022-11-09T18:50:24Z","timestamp":1668019824000},"page":"e0277334","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":2,"title":["A novel pathogenesis concept of biliary atresia approached by combined molecular strategies"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2475-6772","authenticated-orcid":true,"given":"Wison","family":"Laochareonsuk","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Komwit","family":"Surachat","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piyawan","family":"Chiengkriwate","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3622-3233","authenticated-orcid":true,"given":"Surasak","family":"Sangkhathat","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2022,11,9]]},"reference":[{"key":"pone.0277334.ref001","first-page":"112","article-title":"Biliary atresia\u2014signs and symptoms, diagnosis, clinical management","volume":"70","author":"E Orlowska","year":"2017","journal-title":"Wiad Lek"},{"key":"pone.0277334.ref002","doi-asserted-by":"crossref","first-page":"367","DOI":"10.1001\/archsurg.1974.01360030019005","article-title":"Biliary atresia.
