The detected CGH anomalies included a 22q11del, 1p36del, a 2p21del of unknown significance, and a 2p13.3-p16.3duplication. We fine mapped a subgroup of bilateral perisylvian polymicrogyria (BPP) patients to 2p16.1-p16.3. We identified a novel TUBB2B mutation in exon 4 in a sporadic patient with PMG and associated anomalies of the basal ganglia and brainstem; neither parent carried this mutation.CONCLUSIONS: Polymicrogyria is markedly heterogeneous. Our results support previous suggestions of PMG loci on chromosomes 22q11 and 1p36. We have narrowed a novel locus for BPP to 2p13.1-p16.3. These data can help to identify the causative genes located in these regions. We found a novel and de novo TUBB2B mutation in a patient with complex PMG. Identification of associated brain malformations and phenotypic anomalies can help to orient the genetic diagnosis.Supported by: Children{\textquoteright}s Hospital Boston (CHB), Division of Genetics; R{\'e}seau de M{\'e}decine G{\'e}n{\'e}tique Appliqu{\'e}e, Quebec.Disclosure: Dr. Amrom has nothing to disclose.
