Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0024 in 278492 control chromosomes in the gnomAD database, including 4 homozygotes. The observed variant frequency is approximately 5.7 fold of the estimated maximal expected allele frequency for a pathogenic variant in PKP2 causing Arrhythmia phenotype (0.00043), strongly suggesting that the variant is benign. c.1577C>T has been reported in the literature in individuals affected with Arrhythmia. These data do not allow any conclusion about variant significance. Co-occurrences with other pathogenic variant(s) have been reported (PKP2, p.L452*; DSP c.969_974delAAAAGA, p.E324_K325del; DES c.359C>A, p.A120D), providing supporting evidence for a benign role. (Rasmussen 2014, Rasmussen 2013, Brodehl 2013). These authors proposed that the variant of interest might modify the phenotype of other pathogenic variants (Rasmussen 2013) although no conclusive evidence supporting this notion has been published. Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and classified the variant as benign (1x), likely benign (4x) or VUS (1x). Based on the evidence outlined above, the variant was classified as likely benign.
