One in silico tool predicts a damaging outcome for this variant. 4/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 85/38144 control chromosomes (2 homozygotes), predominantly observed in the African subpopulation at a frequency of 0.02059 (81/3934). This frequency is about 374 times the estimated maximal expected allele frequency of a pathogenic RYR2 variant (0.000055), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign.
