Four affected children from two families presenting with pontocerebellar hypoplasiawith neonatal seizures, severe ID and motor delay. Two homozygous splice variants were reported (c.5051–1G>A and c.5050+4A>G) in intron 31 of HEATR5B gene. Aberrant splicing was found in patient fibroblasts, which correlated with reduced levels of HEATR5B protein. Homozygous knockout mice were not viable
