gnomAD and TOPMED databases gather previously reported variation frequencies. GERP tool display a conservation score for a nucleotide position, values above 3 are considered as highly conserved. CADD tool scores the predicted deleteriousness of a variant (SNP or indels), values above 20 can be considered as “likely deleterious”. REVEL method combines 13 individual tools to predict the pathogenicity of missense variants, with scores from 0 to 1, it is estimated “likely disease causing” when above 0.5
