Table 2. Summary description of the annotations provided by VaRank using Alamut Batch.

Column name Annotation
VariantID Variant identifier [#chr]_[genomicposition]_[RefBase]_[VarBase]
Gene Gene symbol
omimId OMIM® id
TranscriptID RefSeq transcript id
TranscriptLength Length of transcript (full cDNA length)
Chr Chromosome of variant
Start Start position of variant
End End position of variant
Ref Nucleotide sequence in the reference genome (restricted to 50bp)
Mut Alternate nucleotide sequence (restricted to 50bp)
Uniprot Uniprot
protein Protein id (NCBI)
posAA Amino acid position
wtAA_1 Reference codon
varAA_1 Alternate codon
Phred_QUAL QUAL: The Phred scaled probability that a REF/ALT polymorphism exists at this site given sequencing data. Because the Phred scale is −10 * log(1 − p), a value of 10 indicates a 1 in 10 chance of error, while a 100 indicates a 1 in 10ˆ10 chance. These values can grow very large when a large amount of NGS data is used for variant calling.

SiftPred SIFT prediction
SiftWeight SIFT score ranges from 0 to 1. The amino acid substitution is predicted damaging is the score is <=0.05, and tolerated if the score is >0.05.
SiftMedian SIFT median ranges from 0 to 4.32. This is used to measure the diversity of the sequences used for prediction. A warning will occur if this is greater than 3.25 because this indicates that the prediction was based on closely related sequences. The number should be between 2.75 and 3.5
PPH2pred PolyPhen-2 prediction using HumVar model are either “neutral, possibly damaging, probably damaging” or “neutral, deleterious” depending on the annotation engine.
