Comment on list classification: Green rating agreed by Helen Brittain based on multiple unrelated cases in PMID:30471716.Created: 12 Mar 2019, 12:12 p.m.
Added MACF1 to 'Cerebellar hypoplasia' panel on advice from Helen Brittain after MACF1 was reviewed by Sarah Leigh on the 'Genetic Epilepsy Syndromes' and 'Intellectual disability' panels. PMID:30471716 (Dobyns et al 2018) recognized a complex brainstem malformation in three unrelated children with MACF1 variants. They searched their large brain-malformation databases and found another five children with this malformation (as well as one with a less severe variant). The brain malformation comprised posterior predominant lissencephaly and midline crossing defects consisting of absent anterior commissure and a striking W-shaped brainstem malformation caused by small or absent pontine crossing fibers.
