CADD: Combined Annotation Dependent Depletion (https://cadd.gs.washington.edu/); GnomAD: https://gnomad.broadinstitute.org. PVS1: pathogenic very strong [null variant (nonsense, frameshift, canonical ±1 or 2 splice sites, initiation codon, single, or multiexon deletion) in a gene where LOF is a known mechanism of disease]; PM2: pathogenic moderate 2 [absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium]; PP3: pathogenic supporting 3 [multiple lines of computational evidence support a deleterious effect on the gene or gene product (conservation, evolutionary, splicing impact, etc.)]; PP5: pathogenic supporting 5 [reputable source recently reports variant as pathogenic, but the evidence is not available to the laboratory to perform an independent evaluation]; BP4: benign supporting 4 [benign computational verdict because of 1 benign prediction from GERP vs. no pathogenic predictions].
