Genetic Epilepsy v0.563 AFG3L2 Zornitza Stark Marked gene: AFG3L2 as ready
Genetic Epilepsy v0.563 AFG3L2 Zornitza Stark Added comment: Comment when marking as ready: The two families reported with ballelic variants appear distantly related. One family with mono-allelic variant.
Genetic Epilepsy v0.563 AFG3L2 Zornitza Stark Gene: afg3l2 has been classified as Red List (Low Evidence).
Genetic Epilepsy v0.560 AFG3L2 Bryony Thompson gene: AFG3L2 was added
gene: AFG3L2 was added to Genetic Epilepsy. Sources: Expert list
Mode of inheritance for gene: AFG3L2 was set to BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Publications for gene: AFG3L2 were set to 25401298; 22022284; 25927548
Phenotypes for gene: AFG3L2 were set to Spastic ataxia 5, autosomal recessive MIM#614487; Spinocerebellar ataxia 28 MIM#610246
Review for gene: AFG3L2 was set to AMBER
Added comment: Currently two clear-cut reports of PME associated with biallelic variants in this gene. Two Italian patients with the same homozygous variant (found to be related through identity by decent analysis), who presented with severe progressive myoclonus at age 10 years after normal early development. Progressive myoclonic epilepsy found to be a feature of the phenotype in a consanguineous family with a homozygous variant. Family with a homozygous SETX variant and a heterozygous AFG3L2 variant with ataxia with postural/intentional myoclonus and involuntary movements, where the myoclonus phenotype appears to be segregating with the AFG3L2 variant.
