AL = Academic Laboratory; CI = confidence interval; RL = reference laboratory; LP/P = likely pathogenic and pathogenic mutations; RR = relative risk; TCGA = The Cancer Genome Atlas; VUS = variants of uncertain significance.
gnomAD v2.1.1 noncancer, 134 187 sample data for TP53 were downloaded and TP53 variants classified as LP/P mutations as per ClinVar or VUS/LP in ClinVar, classified as likely pathogenic in this study. The rate of LP/P and VUS/LP TP53 variants in gnomAD was 0.059%, and the rate of ClinVar LP/P TP53 variants in gnomAD was 0.026%.
