Identification of Variant Alleles at CODIS STR loci in Different Populations of India

Two population's DNA profiling was screened for variant alleles not included within the allelic ladder provided by the manufacturer of GenePrint STR system (Promega Corporation, Madison, US). A total of 3 variant alleles were identified at 3 out of 12 STR loci tested. This study identified one variant allele at TH01 locus (allele 8.3), one at TPOX locus (allele 14) and one at vWA locus (allele 21). All these alleles have been reported previously in different populations. Allele 8.3 found at TH01 fell within the allelic range while allele 14 found at TPOX and allele 21 found at vWA fell outside the allelic range.
