title: The impact of mtDNA analysis between positions nt8306 and nt9021 for forensic casework.
abstract: Identification in forensic casework by mtDNA sequencing is predominantly done by sequencing the non-coding control region (HVI and HVII). In an attempt to further increase the discriminatory power of mtDNA analysis, we sequenced a coding region between nt8306 and nt9021 to identify additional polymorphisms in a group of 61 unrelated German individuals who had mtDNA profiles that occurred more than two times each, as well as a control group of 119 unrelated Germans whose profiles occurred one or two times each. Within these 180 individuals, 38 different polymorphisms in this region were observed; 64.4% of these individuals displayed the Cambridge reference sequence profile plus A8860G. For 28 individuals with the two most common profiles, A263G-315.1insC (N = 18) and A263G-309.1insC-315.1insC (N = 10), additional polymorphisms in this coding region permitted further discrimination of 56 and 40% of the individuals, respectively.
