Comment on list classification: Upgrading from Amber to Green on this 100K panel as there are three unrelated cases (2 published, 1 NHS-diagnosed) with pontocerebellar hypoplasia due to biallelic variants in this gene.Created: 17 Oct 2025, 2:06 p.m. | Last Modified: 17 Oct 2025, 2:06 p.m.
Panel Version: 1.81
As per review by Karen Stals, we have received confirmation of an unpublished NHS-diagnosed family, with three affected individuals presenting with pontocerebellar hypoplasia. The variant, present in a homozygous state in the affected individuals, had a splicing impact and confirmed out-of-frame skipping of exon 30.Created: 17 Oct 2025, 2:04 p.m. | Last Modified: 17 Oct 2025, 2:04 p.m.

Karen Stals (Royal Devon and Exeter Hospital)
Four affected children from two families presenting with pontocerebellar hypoplasia with neonatal seizures, severe ID and motor delay reported by Ghosh et al 2021. Additional family identified through the R14 WGS service in the Exeter Genomics Laboratory with the causative variant co-segregating in multiple affected family members.Created: 26 Apr 2023, 11:56 p.m. | Last Modified: 27 Apr 2023, 12:01 a.m.

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.Created: 14 Jul 2021, 1:40 p.m. | Last Modified: 14 Jul 2021, 1:40 p.m.

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
