Early onset or syndromic epilepsy v2.531 RYR2 Sarah Leigh edited their review of gene: RYR2: Added comment: PMID: 33897349 reports seven RYR2 variants in five unrelated cases of benign epilepsy of childhood with centrotemporal spikes (BECTS). Three of the affected individuals (cases 1,2 & 3) were heterozygous for a RYR2 variant, in one case (case 2) the variant was de novo and in the remaining cases RYR2 variant had been inherited from an unaffected parent. The remaining two individuals (cases 4 & 5) were compound heterozygous inheriting the RYR2 variants from each parent, who were unaffected apart form the father of case 5, who had arrhythmia.; Changed publications to: 33897349

Early onset or syndromic epilepsy v0.656 RYR2 Sarah Leigh gene: RYR2 was added
gene: RYR2 was added to Genetic Epilepsy Syndromes. Sources: Literature
Mode of inheritance for gene: RYR2 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: RYR2 were set to 27832686; 18483626; 29667327; 11208676; 12093772; 11157710
Phenotypes for gene: RYR2 were set to Ventricular tachycardia, catecholaminergic polymorphic, 1 604772
Review for gene: RYR2 was set to AMBER
Added comment: Associated with phenotype in OMIM and not in Gen2Phen. At least 3 variants identified in cases displaying seizures (PMIDs 29667327 & 18483626), together with a mouse model (PMID 27832686). However, there are numerous cases of Ventricular tachycardia, catecholaminergic polymorphic, 1 604772, with no reports of seizures (PMIDs 11208676, 12093772, 11157710), therefore seizures appear to be a rare feature of this condition.
