We have recently come across a particular geste antagoniste in 5 of 10 patients with pantothenate kinase\u2010associated neurodegeneration (<jats:styled-content style=\"fixed-case\">PKAN<\/jats:styled-content>) who had prominent oromandibular involvement with severe jaw\u2010opening dystonia. It consists of touching the chin with both hands characteristically clenched into a fist with flexion at the elbows. Because of the resemblance of this geste antagoniste with the praying\u2010like posture of <jats:italic>Mantis religiosa<\/jats:italic>, we coined the term \u201cmantis sign.\u201d Reviewing videos of <jats:styled-content style=\"fixed-case\">PKAN<\/jats:styled-content> cases in literature, including what is considered the first cinematic depiction of a case of this disorder, 3 additional cases with akin maneuvers were identified. In contrast, examining 205 videos of non\u2010<jats:styled-content style=\"fixed-case\">PKAN<\/jats:styled-content> dystonic patients from our database for the presence of a similar maneuver was unrevealing. Thus, we consider the mantis sign to be quite typical of <jats:styled-content style=\"fixed-case\">PKAN<\/jats:styled-content> and propose it to be added as a clinical hint toward
