Flanking microhomology
WebFlanking Region Variation. Flanking region variation can also give rise to apparent “off-ladder” alleles. One of the best examples of this phenomenon is found in the STR locus … WebHere we show microhomologies are identified by a scanning mechanism initiated from the 3′ terminus and favoring bidirectional progression into flanking DNA, typically to a maximum of 15 nucleotides into each flank. Polymerase theta is frequently insufficiently processive to complete repair of breaks in microhomology-poor, AT-rich regions.
