If, for instance, subject has in his genome IGHV1-2*02
and a novel
allele equally close to IGHV1-2*02
and IGHV1-2*05
, the novel allele may be
detected by analyzing sequences that best align to either of these alleles.
If keep_alleles
is TRUE
, both polymorphic allele calls will
be retained. In the case that multiple mutation ranges are checked for the
same allele, only one mutation range will be kept in the output.
