Sarah Leigh (Genomics England Curator)

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 RYR2 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.

Green List (high evidence)

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.
