Mendeliome v1.2482 USP25 Zornitza Stark Classified gene: USP25 as Amber List (moderate evidence)
Mendeliome v1.2482 USP25 Zornitza Stark Gene: usp25 has been classified as Amber List (Moderate Evidence).
Mendeliome v1.2479 USP25 Sangavi Sivagnanasundram edited their review of gene: USP25: Added comment: This gene-disease association has been DISPUTED by ClinGen Epilepsy GCEP on 01/04/2025 - https://search.clinicalgenome.org/CCID:008786

ClinGen's reason for disuputed classification - "Case-level data was not considered strong enough to score. Functional data was not consistent among the variants and was difficult to interpret in relationship to a seizure phenotype. The knock-out mouse model did not exhibit spontaneous seizures so was not scored."

Downgrade to Amber due to the uncertainty was agreed within the user group.; Changed rating: AMBER; Changed phenotypes: USP25-related epilepsy (epilepsy MONDO:0005027)
Mendeliome v1.2267 USP25 Zornitza Stark Phenotypes for gene: USP25 were changed from USP25-related epilepsy (epilepsy, idiopathic generalized, MONDO:0005579) to {Epilepsy, idiopathic generalized, susceptibility to, 19} MIM#621064
Mendeliome v1.1871 USP25 Zornitza Stark Marked gene: USP25 as ready

Review for gene: USP25 was set to GREEN
Added comment: PMID: 38875478
5 heterozygous variants were identified in 8 individuals from 5 unrelated families all with clinical phenotypes associated with generalised epilepsy.

Knock-out mouse model showed increased seizure susceptibility compared to the WT.
Both loss of function and gain of function variants can be a mechanism of disease in individuals with USP25-related epilepsy.
