Abstract
Pediatric and perinatal stroke can present as an early symptom in undiagnosed syndromes characterized by simple Mendelian inheritance. In order to diagnose those patients affected with a monogenic disorder in which an arterial cerebrovascular event or arteriopathy may have preceded any other specific symptom, we aimed to establish and validate a targeted gene panel, and to determine its diagnostic yield and clinical utility. To this end, thirty-eight patients were selected with heterogeneous cryptogenic stroke phenotypes, mostly including multiple and recurrent ischemic or hemorrhagic arterial strokes and porencephalies, variably associated with calcifications, intracranial or multisystem steno-occlusive arteriopathies, positive family history, and syndromic conditions. Clinical and neuroradiological data were collected for every patient enrolled in the study, and DNA samples were tested by means of a customized gene panel including 15 genes associated with known genetic diseases related to pediatric stroke. In four patients (10.5%) the analyses unraveled pathogenetic variants in ABCC6 and COL4A1 genes, leading to a definite genetic diagnosis with a great beneficial impact on patients ...
