Previous work has suggested potential genetic and phenotypic overlap between dysregulation of Ras\/MAPK signalling and autism spectrum disorders (ASD). Although the literature offers conflicting evidence for association of NF1 and autism, there has been no systematic evaluation of autism traits in the RASopathies as a class to support a role for germline Ras\/MAPK activation in ASDs.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>We examined the association of autism traits with NF1, NS, CS and CFC, comparing affected probands with unaffected sibling controls and subjects with idiopathic ASDs using the qualitative Social Communication Questionnaire (SCQ) and the quantitative Social Responsiveness Scale (SRS).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Each of the four major RASopathies showed evidence for increased qualitative and quantitative autism traits compared with sibling controls. Further, each RASopathy exhibited a distinct distribution of quantitative social impairment. Levels of social responsiveness show some evidence of correlation between sibling pairs, and autism-like impairment showed a male bias similar to idiopathic ASDs.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Higher prevalence and severity of autism traits in RASopathies compared to unaffected siblings suggests that dysregulation of Ras\/MAPK signalling during development may be implicated in ASD risk. Evidence for sex bias and potential sibling correlation suggests that autism traits in the RASopathies share characteristics with autism traits in the general population and clinical ASD population and can shed light on idiopathic ASDs.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/jmedgenet-2013-101951","type":"journal-article","created":{"date-parts":[[2013,10,7]],"date-time":"2013-10-07T20:16:35Z","timestamp":1381176995000},"page":"10-20","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":166,"title":["Autism traits in the RASopathies"],"prefix":"10.1136","volume":"51","author":[{"given":"Brigid","family":"Adviento","sequence":"first","affiliation":[{"name":"Department of Psychiatry, University of California San Francisco, San Francisco, California, USA"},{"name":"Institute for Human Genetics, University of California San Francisco, San Francisco, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iris L","family":"Corbin","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of California San Francisco, San Francisco, California, USA"},{"name":"Institute for Human Genetics, University of California San Francisco, San Francisco, California, USA"},{"name":"Prenatal Diagnosis Center, Sutter Pacific Medical Foundation, San Francisco, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felicia","family":"Widjaja","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of California San Francisco, San Francisco, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillaume","family":"Desachy","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of California San Francisco, San Francisco, California, USA"},{"name":"Institute for Human Genetics, University of California San Francisco, San Francisco, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicole","family":"Enrique","sequence":"additional","affiliation":[{"name":"Department of Psychology, Semel Institute for Neuroscience and Human Behavior, University of California Los Angeles, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tena","family":"Rosser","sequence":"additional","affiliation":[{"name":"Department of Neurology, Children's Hospital Los Angeles, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan","family":"Risi","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of California San Francisco, San Francisco, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elysa J","family":"Marco","sequence":"additional","affiliation":[{"name":"Department of Child Neurology, University of California San Francisco, San Francisco, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert L","family":"Hendren","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of California San Francisco, San Francisco, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carrie E","family":"Bearden","sequence":"additional","affiliation":[{"name":"Department of Psychology, Semel Institute for Neuroscience and Human Behavior, University of California Los Angeles, Los Angeles, California, USA"},{"name":"Department of Psychology, University of California Los Angeles, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine A","family":"Rauen","sequence":"additional","affiliation":[{"name":"Institute for Human Genetics, University of California San Francisco, San Francisco, California, USA"},{"name":"Department of Pediatrics Genetics, University of California San Francisco, San Francisco, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren A","family":"Weiss","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of California San Francisco, San Francisco, California, USA"},{"name":"Institute for Human Genetics, University of California San Francisco, San Francisco, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2013,10,7]]},"reference":[{"key":"2025100521263428000_51.1.10.1","unstructured":"Blumberg S Bramlett M Kogan MD Schieve L Jones J Lu M .
