|A detection model parameter to describe a set of mapped insertion mutations. A insertion mutation refers to the addition of one or more nucleotides to a DNA strand. In publications, insertion mutations may be reported in nucleotide or in peptide format. Insertion mutations not of a multiple of 3 cause frameshifts in the nucleotide open reading frame. However, the insertion mutation parameter only refers to insertions which modify the peptide sequence and/or change its function, but do not result in premature termination or functional protein knockout.
