SCAD mainly affects women and is associated with pregnancy and systemic arteriopathies, particularly fibromuscular dysplasia. Variants in several genes, such as those causing connective tissue disorders, have been implicated; however, the genetic architecture is poorly understood. Here, we aim to better understand the diagnostic yield of rare variant genetic testing among a cohort of SCAD survivors and to identify genes or gene sets that have a significant enrichment of rare variants.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>We sequenced a cohort of 384 SCAD survivors from the United Kingdom, alongside 13\u2009722 UK Biobank controls and a validation cohort of 92 SCAD survivors. We performed a research diagnostic screen for pathogenic variants and exome-wide and gene-set rare variant collapsing analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>The majority of patients within both cohorts are female, 29% of the study cohort and 14% validation cohort have a remote arteriopathy. Four cases across the 2 cohorts had a diagnosed connective tissue disorder. We identified pathogenic or likely pathogenic variants in 7 genes (<jats:italic>PKD1<\/jats:italic>,<jats:italic>COL3A1<\/jats:italic>,<jats:italic>SMAD3<\/jats:italic>,<jats:italic>TGFB2<\/jats:italic>,<jats:italic>LOX<\/jats:italic>,<jats:italic>MYLK<\/jats:italic>, and<jats:italic>YY1AP1<\/jats:italic>) in 14\/384 cases in the study cohort and in 1\/92 cases in the validation cohort. In our rare variant collapsing analysis,<jats:italic>PKD1<\/jats:italic>was the highest-ranked gene, and several functionally plausible genes were enriched for rare variants, although no gene achieved study-wide statistical significance. Gene-set enrichment analysis suggested a role for additional genes involved in renal function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>By studying the largest sequenced cohort of SCAD survivors, we demonstrate that, based on current knowledge, only a small proportion have a pathogenic variant that could explain their disease. Our findings strengthen the overlap between SCAD and renal and connective tissue disorders, and we highlight several new genes for future validation.<\/jats:p><\/jats:sec>","DOI":"10.1161\/circgen.120.003030","type":"journal-article","created":{"date-parts":[[2020,10,30]],"date-time":"2020-10-30T16:00:19Z","timestamp":1604073619000},"source":"Crossref","is-referenced-by-count":71,"title":["Spontaneous Coronary Artery Dissection"],"prefix":"10.1161","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4939-156X","authenticated-orcid":true,"given":"Keren J.","family":"Carss","sequence":"first","affiliation":[{"name":"Centre for Genomics Research, Discovery Sciences, BioPharmaceuticals R&amp;D, AstraZeneca (K.J.C., J.A., Q.W., S.V.V.D., D.V., S.H.L., S.P., C.H.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0827-6792","authenticated-orcid":true,"given":"Anna A.","family":"Baranowska","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences and NIHR Leicester Biomedical Research Centre, University of Leicester, United Kingdom (A.A.B., T.R.W., S.E.H., D.P., A.A.-H., A.W., D.K., N.J.S., D.A.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Armisen","sequence":"additional","affiliation":[{"name":"Centre for Genomics Research, Discovery Sciences, BioPharmaceuticals R&amp;D, AstraZeneca (K.J.C., J.A., Q.W., S.V.V.D., D.V., S.H.L., S.P., C.H.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5998-8226","authenticated-orcid":true,"given":"Tom R.","family":"Webb","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences and NIHR Leicester Biomedical Research Centre, University of Leicester, United Kingdom (A.A.B., T.R.W., S.E.H., D.P., A.A.-H., A.W., D.K., N.J.S., D.A.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6215-5791","authenticated-orcid":true,"given":"Stephen E.","family":"Hamby","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences and NIHR Leicester Biomedical Research Centre, University of Leicester, United Kingdom (A.A.B., T.R.W., S.E.H., D.P., A.A.-H., A.W., D.K., N.J.S., D.A.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diluka","family":"Premawardhana","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences and NIHR Leicester Biomedical Research Centre, University of Leicester, United Kingdom (A.A.B., T.R.W., S.E.H., D.P., A.A.-H., A.W., D.K., N.J.S., D.A.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abtehale","family":"Al-Hussaini","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences and NIHR Leicester Biomedical Research Centre, University of Leicester, United Kingdom (A.A.B., T.R.W., S.E.H., D.P., A.A.-H., A.W., D.K., N.J.S., D.A.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4208-6802","authenticated-orcid":true,"given":"Alice","family":"Wood","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences and NIHR Leicester Biomedical Research Centre, University of Leicester, United Kingdom (A.A.B., T.R.W., S.E.H., D.P., A.A.-H., A.W., D.K., N.J.S., D.A.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7717-4058","authenticated-orcid":true,"given":"Quanli","family":"Wang","sequence":"additional","affiliation":[{"name":"Centre for Genomics Research, Discovery Sciences, BioPharmaceuticals R&amp;D, AstraZeneca (K.J.C., J.A., Q.W., S.V.V.D., D.V., S.H.L., S.P., C.H.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0405-4335","authenticated-orcid":true,"given":"Sri V.
