Skin manifestations are readily visible, often develop early in life, and are major features that contribute to TSC diagnosis. Medical photographs of such manifestations are commonly shown as examples from White individuals creating a potential barrier to accurately identifying these features in darker skinned individuals.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives:<\/jats:title>\n                    <jats:p>The aim of this report is to raise awareness of dermatological manifestations associated with TSC, compare their appearance by race, and consider how recognition of these features could impact diagnosis and treatment of TSC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design and Methods:<\/jats:title>\n                    <jats:p>We conducted a retrospective chart review at the TSC Center of Excellence (TSCOE) at the Kennedy Krieger Institute, which included all patients in the center from 2009 (inception) through the end of the calendar year 2015 and analyzed data from the TSC Alliance Natural History Database (NHD).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Among TSCOE patients, 50% of Black patients were diagnosed before the age of 1 year, compared with 70% of White patients. NHD data corroborated this trend showing a significant difference with only 38% of Blacks as compared with 50% of Whites were diagnosed at age \u2a7d1 year. A significant difference was observed where White participants had higher odds of having received genetic testing in both data sets. While no differences in the total number of TSC features was observed in either data set, shagreen patches and cephalic fibrous plaques were more frequently recorded in the NHD for Black individuals.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>We highlight a disparity in the representation of Black participants within the NHD, TSCOE, and TSC trials, in addition to differences in utilization of molecular testing and topical mechanistic target of rapamycin (mTOR) inhibitor therapy between Black and White individuals. We show a trend toward later diagnosis age in Black individuals. These differences between races warrant further study across additional clinical sites and other minority groups.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/26330040221140125","type":"journal-article","created":{"date-parts":[[2022,12,10]],"date-time":"2022-12-10T04:12:53Z","timestamp":1670645573000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Racial differences in the dermatological manifestations of tuberous sclerosis complex and the potential effects on diagnosis and care"],"prefix":"10.1177","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9582-6360","authenticated-orcid":false,"given":"Ashley J.","family":"Pounders","sequence":"first","affiliation":[{"name":"TSC Alliance, Silver Spring, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6114-883X","authenticated-orcid":false,"given":"Gabrielle V.","family":"Rushing","sequence":"additional","affiliation":[{"name":"TSC Alliance, Silver Spring, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonal","family":"Mahida","sequence":"additional","affiliation":[{"name":"Department of Neurology, Boston Children\u2019s Hospital, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bareng Aletta Sanny","family":"Nonyane","sequence":"additional","affiliation":[{"name":"Department of Neurology and Developmental Medicine, Kennedy Krieger Institute, Baltimore, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily A.","family":"Thomas","sequence":"additional","affiliation":[{"name":"Department of International Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rabiah Sundus","family":"Tameez","sequence":"additional","affiliation":[{"name":"Arkansas College of Osteopathic Medicine, Fort Smith, AR, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6903-743X","authenticated-orcid":false,"given":"Tanjala T.","family":"Gipson","sequence":"additional","affiliation":[{"name":"TSC Center of Excellence, Le Bonheur Children\u2019s Hospital, 50 N.
