One in silico tool predicts a damaging outcome for this variant. 5/5 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 85/113904 control chromosomes, predominantly observed in the African subpopulation at a frequency of 0.0086377 (79/9146). This frequency is about 346 times the estimated maximal expected allele frequency of a pathogenic CAV3 variant (0.000025), 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 likely benign/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.
