GFAP and dysautonomia: It is noteworthy that neither the familial case reported by Casasnovas et al. [17] nor our patient carrying the p/Gly18Val mutation in the GFAP gene exhibited bulbar symptoms such as dysphagia, dysarthria, or palatal myoclonus, which are typical for AOAD [3], nor did they present with features of dysautonomia.
