Kristin Rigbye (Victorian Clinical Genetics Services)
Many reports of missense and PTC variants resulting in a LoF, in individuals with Feingold syndrome, of which microcephaly is a key feature.
Only a single report of a de novo missense showing a GoF in an individual with a novel megalencephaly syndrome (megalencephaly, ID, ventriculomegaly, hypoplastic corpus callosum, polydactyly and neuroblastoma)Created: 21 May 2021, 1:55 a.m. | Last Modified: 21 May 2021, 1:55 a.m.
