Twin and family studies have suggested that genetics contributes to disease progression. However, the genetic causes of familial LSS remain unclear. We performed whole-exome and direct sequencing on seven female patients from a Han Chinese family with LBP, among whom four developed LSS. Based on our genetic findings, we performed gene knockdown studies in human chondrocytes to study possible pathological mechanisms underlying LSS. We found a novel nonsense mutation, c.417C &gt; G (NM_002183, p.Y139X), in IL3RA, shared by all the LBP\/LSS cases. Knockdown of IL3RA led to a reduction in the total collagen content of 81.6% in female chondrocytes and 21% in male chondrocytes. The expression of MMP-1, -3, and\/or -10 significantly increased, with a more pronounced effect observed in females than in males. Furthermore, EsRb expression significantly decreased following IL3RA knockdown. Moreover, the knockdown of EsRb resulted in increased MMP-1 and -10 expression in chondrocytes from females. We speculate that IL3RA deficiency could lead to a reduction in collagen content and intervertebral disk (IVD) strength, particularly in females, thereby accelerating IVD degeneration and promoting LSS occurrence. Our results illustrate, for the first time, the association between IL3RA and estrogen receptor beta, highlighting their importance and impact on MMPs and collagen in degenerative spines in women.<\/jats:p>","DOI":"10.3390\/ijms252010915","type":"journal-article","created":{"date-parts":[[2024,10,10]],"date-time":"2024-10-10T11:34:36Z","timestamp":1728560076000},"page":"10915","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Role of IL3RA in a Family with Lumbar Spinal Stenosis"],"prefix":"10.3390","volume":"25","author":[{"given":"Kai-Ming","family":"Liu","sequence":"first","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chi-Fan","family":"Yang","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0571-258X","authenticated-orcid":false,"given":"Weng-Siong","family":"H\u2019ng","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hui-Ping","family":"Chuang","sequence":"additional","affiliation":[{"name":"Resource Center for Translational Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eunice Han Xian","family":"Khor","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pei-Chun","family":"Tsai","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6451-3556","authenticated-orcid":false,"given":"Vivia","family":"Khosasih","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang-Suei","family":"Lu","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erh-Chan","family":"Yeh","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wan-Jia","family":"Lin","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng-Jen","family":"Hsieh","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chien-Hsiun","family":"Chen","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiuh-Lin","family":"Hwang","sequence":"additional","affiliation":[{"name":"Chi Hsien Spine Hospital, Kaohsiung 800, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jer-Yuarn","family":"Wu","sequence":"additional","affiliation":[{"name":"National Center for Genome Medicine, Institute of Biomedical Sciences, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"789","DOI":"10.31616\/asj.2022.0366","article-title":"Lumbar Spinal Stenosis: Review Update 2022","volume":"16","author":"Kwon","year":"2022","journal-title":"Asian Spine J."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"392","DOI":"10.1038\/nrneurol.2009.90","article-title":"Lumbar spinal stenosis: Syndrome, diagnostics and treatment","volume":"5","author":"Siebert","year":"2009","journal-title":"Nat.
