Malformations in the central nervous system typically involve midline structures and reflect abnormal growth and differentiation of neurons and supporting cells. Despite these defects in central nervous system development, brain tumor formation has only rarely been reported in association with SLOS. We present three individuals with SLOS and lesions in the basal ganglia or brainstem detected by MRI that were concerning for tumor formation. However, the individuals\u2019 clinical and neurological course remained stable, and the lesions regressed after several years. These lesions have similarities to spongiotic changes observed in individuals with neurofibromatosis type 1 (NF1). Notably, impaired activity of small GTPases is present in both SLOS and NF1, perhaps giving mechanistic insight into the formation of these lesions.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ajmg.a.38563","type":"journal-article","created":{"date-parts":[[2017,12,11]],"date-time":"2017-12-11T05:36:54Z","timestamp":1512970614000},"page":"386-390","source":"Crossref","is-referenced-by-count":6,"title":["Spontaneously regressing brain lesions in Smith\u2013Lemli\u2013Opitz syndrome"],"prefix":"10.1002","volume":"176","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4171-0493","authenticated-orcid":false,"given":"An N.","family":"Dang Do","sequence":"first","affiliation":[{"name":"Division of Translational Research, Eunice Kennedy Shriver National Institute of Human Development (NICHD) National Institutes of Health Bethesda Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva H.","family":"Baker","sequence":"additional","affiliation":[{"name":"Department of Radiology and Imaging Sciences Clinical Center National Institutes of Health Bethesda Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine E.","family":"Warren","sequence":"additional","affiliation":[{"name":"Center for Cancer Research National Cancer Institute National Institutes of Health Bethesda Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simona E.","family":"Bianconi","sequence":"additional","affiliation":[{"name":"Division of Translational Research, Eunice Kennedy Shriver National Institute of Human Development (NICHD) National Institutes of Health Bethesda Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Forbes D.","family":"Porter","sequence":"additional","affiliation":[{"name":"Division of Translational Research, Eunice Kennedy Shriver National Institute of Human Development (NICHD) National Institutes of Health Bethesda Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,12,11]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00019052-200404000-00004"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-016-3214-z"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320280320"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nicl.2014.04.005"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00695225"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1134"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320260110"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.195.3.7754001"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.5694\/j.1326-5377.2010.tb03904.x"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/nm.4067"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-006-0267-2"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPH.0b013e318180bbb9"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.4161\/cc.3.10.1182"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/ddq011"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.282.1.36"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.37.5.321"},{"issue":"10","key":"e_1_2_7_18_1","doi-asserted-by":"crossref","first-page":"2407","DOI":"10.1002\/ajmg.a.36096","article-title":"Brain magnetic resonance imaging findings in Smith\u2010Lemli\u2010Opitz syndrome","volume":"161","author":"Lee R.
