GeneDx RCV000182886 SCV000235275 uncertain significance not provided 2019-01-11 criteria provided, single submitter clinical testing The S3938R variant of uncertain significance in the RYR2 gene has been reported in a 12 year-old Caucasian male with exertional sudden cardiac arrest and no known family history of CPVT; however, the specific nucleotide change was not provided (Roston et al., 2018). S3938R, due to a different nucleotide change (c.11814 C>A), has been published in association with CPVT (Tester et al., 2006). The S3938R variant is not observed in large population cohorts (Lek et al., 2016). S3938R is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. Moreover, in-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. Finally, the S3938R variant is located in one of the three hot-spot regions of the RYR2 gene, where the majority of pathogenic missense variants occur (Medeiros-Domingo et al., 2009).Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or rare benign.
