EEG findings in TUBA1A, TUBB2 and TUBB3 genes mutations. Patient A [P89815] (33 months) has a mutation in TUBA1A gene and at MRI multifocal PMG. During drowsiness: asymmetric background activity (square: a). Paroxysmal slow abnormalities over right posterior regions (square: b). Asynchronous epileptiform abnormalities over left central areas (square: c). Patient B [P76712] (8 years) has a mutation in TUBB2B gene. B1 EEG during wakefulness: asymmetry of the background activity and paroxysmal slow abnormalities over left centro-temporal areas (square: d). B2 EEG during drowsiness: epileptiform abnormalities over left centro-temporal areas (square e). Patient’s MRI showed a schizencephaly in left centro-temporal areas consistent to EEG abnormalities. Patient C [P105814] (15 months) has a mutation in TUBB3 gene. EEG during 2-3 non-REM sleep: asymmetric and asynchronous background activity (square f). Diphasic slow abnormalities over right parietal and occipital areas (square g). In this patient, no epileptiform abnormalities were recorded according with the absence of MCDs on MRI.
