Intellectual disability - microarray and sequencing v3.1594 RYR2 Sarah Leigh changed review comment from: PMID: 30170228 reports 34/421 RYR2-associated catecholaminergic polymorphic ventricular tachycardia (CPVT1) patients had intellectual disability. It was also possible to establish that de novo variants had arisen in 13/24 of these cases. RYR2 has not been made green on this panel at present, as ID is not a common feature of CPVT1 and it would appear that penetrance is incomplete.; to: PMID: 30170228 reports 34/421 RYR2-associated catecholaminergic polymorphic ventricular tachycardia (CPVT1) patients had intellectual disability.

Intellectual disability - microarray and sequencing v3.1594 RYR2 Sarah Leigh Classified gene: RYR2 as Amber List (moderate evidence)
Intellectual disability - microarray and sequencing v3.1594 RYR2 Sarah Leigh Gene: ryr2 has been classified as Amber List (Moderate Evidence).
Intellectual disability - microarray and sequencing v3.1593 RYR2 Sarah Leigh Tag Q3_22_rating was removed from gene: RYR2.
Tag Q3_22_expert_review was removed from gene: RYR2.
Intellectual disability - microarray and sequencing v3.1593 RYR2 Sarah Leigh Tag Q3_22_rating tag was added to gene: RYR2.
Tag Q3_22_expert_review tag was added to gene: RYR2.
Intellectual disability - microarray and sequencing v3.1593 RYR2 Dmitrijs Rots gene: RYR2 was added
gene: RYR2 was added to Intellectual disability. Sources: Literature
Mode of inheritance for gene: RYR2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: RYR2 were set to 30170228
Penetrance for gene: RYR2 were set to Incomplete
Review for gene: RYR2 was set to GREEN
Added comment: In a large cohort of RYR2-related CPVT, 8% of individuals (34 of 421) were having ID of various severity. Funcional data suggest that highly damaging RYR2 variants underlie ID.
