Аннотация:This research draws on a double scope: first is to be a case report (Daniel, 11 years old, medical diagnosis of Autistic Spectrum Disorder); second is because it is guided by the methodological strategy of Institutional Analysis of Discourse (IAD).By IAD, the idea of "case" will be organized from strategic concepts of institution and discourse, as we will consider the "case" as a device that configures a set of discursive practices that, at a given moment and place, produce certain subjectivation effects.Thus, the analysis object (the "case") configured by this methodological-conceptual scope will then be thought as the whole institutional relations context, as well as the different forms of exercise and configuration of institutional places occupied by someone.This someone in this research is Daniel, a boy who has a medical diagnosis of autism but, most importantly, who does not speak.And in the impossibility of speaking, Daniel's speech is body and movement; their expressions, their ways of being and acting, their communication are always by, in and with their body.For this reason, Daniel imposes on this work the condition that it is an analytical study of the subjectivation modes of a boy deprived of speech as a type action on and in the relationships he is involved with.Thus, this research poses a limit question: how to draw the framework of a subjectivity analytics, amidst the materiality of the events of Daniel's history?
