Severe microcephaly
Gene: ZNF668Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). There is currently no phenotypes associated with this gene in OMIM or Gene2Phenotype. As there are only 2 cases there is currently not enough evidence to support a gene-disease association. Therefore, this gene has been given an Amber rating.Created: 6 Oct 2021, 3:36 p.m. | Last Modified: 6 Oct 2021, 3:36 p.m.

2 consanguineous families reported with different biallelic truncating (not NMD) variants in ZNF668. Phenotypes included microcephaly, growth deficiency, severe global developmental delay, brain malformation, and distinct facial dysmorphism.
Immunofluorescence indicated ZNF668 deficiency. An increased DNA damage phenotype was demonstrated in patient fibroblasts.
