Even where DNA sequencing is available, linkage analysis still has a role if no causative or candidate mutation is unveiled. The cumulative heterozygosity rate of the available multiplexed STRs haplotyping assays rarely reaches 100%. This means that in a proportion of women these loci are uninformative. The norm-referenced assessment is based on at least one informative marker criterion. We reasoned that by typing a dense market set, spanning a small fraction of recombination, we should be able to improve assessment. The aim of this study was to improve criterion-referenced assessment in polymorphism segregation analyses using a low-recombination fraction and dense informative STRs set. The multiplex quantitative fluorescence PCR assay comprises four novel tetranucleotide and pentanucleotide STRs distant < or = 0.15 cM from the F8 gene, and three F8 intragenic dinucleotide STRs, mapped to a 0.23 cM interval spanning the F8 on human chromosome band Xq28. We determined heterozygosity rates and allele frequencies from 100 unrelated healthy females. To investigate about segregation stability, we typed 50 true trios (mother, daughter and father) and 50 true mother-and-son duos from the general population. The heterozygosity rates for the extragenic markers ranged 0.49-0.76. The 0.23 cM-resolution heptaplex rendered a cumulative heterozygosity of 0.89 for a minimum of two informative markers, with at least one F8 intragenic. The heptaplex assay enabled improving the criterion-referenced assessment in indirect carrier-detection."xsd:string |
