I don't know

Green R29, usually de novo variants, PMID:32197073 reported 6 unrelated individuals, 5 proven de novo variants. Neurodevelopment with/without or brain anomolies, thin corpus callosum, Cortical atrophy, White matter loss, Cerebellar volume loss, Type I Chiari malformation. No evidence detected prenatally in paper. Amber - more evidence of prenatal phenotype required.
