Efficient human paternity testing with a panel of 40 short insertion-deletion polymorphisms

J. R. Pimenta and Pena, S. D. J., Efficient human paternity testing with a panel of 40 short insertion-deletion polymorphisms, vol. 9, pp. 601-607, 2010.

We developed a panel of 40 multiplexed short insertion-deletion (indel) polymorphic loci with widespread chromosomal locations and allele frequencies close to 0.50 in the European population. We genotyped these markers in 360 unrelated self-classified White Brazilians and 50 mother-child-probable father trios with proven paternity. The average heterozygosity (gene diversity) per locus was 0.48, and the combined probability of identity (matching probability) for the 40-locus set was 3.48 x 10-17. The combined power of exclusion of the indel panel was 0.9997.

PedExpert: a computer program for the application of Bayesian networks to human paternity testing

R. R. Gomes, Campos, S. V. A., and Pena, S. D. J., PedExpert: a computer program for the application of Bayesian networks to human paternity testing, vol. 8, pp. 273-283, 2009.

PedExpert is a Windows-based Bayesian network software, especially constructed to solve problems in parentage testing that are complex because of missing genetic information on the alleged father and/or because they involve genetic mutations. PedExpert automates the creation and manipulation of Bayesian networks, implementing algorithms that convert pedigrees and sets of indispensable information (genotypes, allele frequencies, mutation rates) into Bayesian networks.
