Ivone Leong (Genomics England Curator)

Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is not associated with a phenotype in OMIM or Gene2Phenotype. As there is currently not enough evidence to support a gene-disease association this gene has been given an Amber rating.

PMID: 34212451 - 2 unrelated cases with de novo missense variants (p.Pro380Leu and p.Phe425Ser), one case with early-onset refractory epilepsy, severe disability, and progressive cerebral and cerebellar atrophy, and the second case with mild dysmorphism, global developmental delay, and moderate intellectual disability. In vitro biochemical analyses of p.Pro380Leu demonstrated a reduction in protein levels, impaired cellular trafficking, and defective activation of intracellular signaling pathways.
PMID: 31981491 - an autism spectrum disorder (no other information on phenotype, except ascertained to have severe neurodevelopmental delay) case with a de novo missense variant p.(Arg210Leu)
PMID: 12483218 - null mouse model assessing memory demonstrated selective cognitive dysfunction.
