Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is associated with a phenotype in OMIM and Gene2Phenotype. There is enough evidence to support a gene-disease association. This gene should be rated Green at the next review.Created: 6 Dec 2021, 3:59 p.m. | Last Modified: 6 Dec 2021, 3:59 p.m.
Panel Version: 2.108
PMID: 28377535 - Neuroimaging was performed in 44 of 58 individuals: six unrelated individuals (6/44, 14%) showed a consistent MCD intermediate between typical polymicrogyria (PMG) and the cortical appearance of tubulinopathies, consisting of mixed large and small gyri separated by shallow sulci, a smooth grey-white border and little infolding. These individuals also had hypoplastic corpus callosum of varying degrees, enlarged and mildly dysplastic basal ganglia, hippocampal dysplasia with thick leaves and open hilus as well as enlarged tecta. One had no septum pellucidum. Generalised cerebral volume loss, compatible with cerebral atrophy, was described in four additional patients (4/44; 9%).
