Ataxia and cerebellar anomalies - narrow panelGene: HEATR5B
Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is not associated with a phenotype in OMIM or Gene2Phenotype. There is currently not enough evidence to support a gene-disease association. This gene has been given an Amber rating.

Panel Version: 3.1188
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
