The matching of genotype (of the baby) with phenotype (of the living adult) was possible because the mutation ratio of individuals in this family were known.
These mutants have been identified by 246,566 flanking sequence tags (FSTs) and cover 65%% (25,275 of 38,869) of the non-TE genes in rice, while the mutation ratio of TE genes is 25.7%%.
This compound has been observed to induce a mutation ratio of 20.4, suggesting that quercetin contributes to the mutagenic potential of this genus.
Although genetic characterization of tumor tissues demonstrates that mutation of the p53 gene is the most common genetic alteration in human cancers, the mutation ratio of the p53 gene in uterine cervical cancer is relatively low [ 4, 5].
Mutations were randomly introduced by using the PCR-based Genemorph II Random Mutagenisis Kit from Stratagene (La Jolla, CA, USA) and following the manufacture's instructions for achieving a mutation ratio of 1%.
Nonsynonymous nucleotide substitutions detected in these analyses (with thresholds for total coverage of ≥30× and for the mutation ratio of ≥20%) included 56 alterations in 53 independent genes (Table S2).
Mutation ratio of m.5541C > T in the patient was determined as follows: Extracted DNA (1 ng) was used as template for quantitative PCR with TaqMan Universal PCR Master Mix kit (Applied Biosystems) according to the manufacturer's instructions.
The detailed analysis of two of these regions with lengths 4,220 and 4,044 bp and identities of 94% and 89% relative to their nuclear counterparts, showed a transition/transversion mutation ratio of 2.2 and 3.8 respectively, with CMit → TNuc and GMit → ANuc the most abundant mutations found, and CMit → ANuc the most representative transversion mutations.
As such, we analyzed the behavior of nonsynonymous to synonymous mutation ratios as a function of the DAFs of the respective SNPs (supplementary fig. S1, Supplementary Material online).
Rates of recombination, estimated with 12 new loci using ClonalFrame [30], are close to previous reports [28] using five loci with a recombination to mutation ratio (r/m) of 3.8.
