The age of an allele can be estimated both from genetic variation among different copies (intra-allelic variation) and from its frequency. Estimates based on intra-allelic variation follow from the exponential decay of linkage disequilibrium because of recombination and mutation. The confidence interval depends both on the uncertainty in recombination and mutation rates and on randomness of the genealogy of chromosomes that carry the allele (the intra-allelic genealogy). Several approximate…

The distribution of allele age, combined with a model predicting the extent of intra-allelic variability generated by mutation and recombination, leads to a statistical test of whether a rare allele has experienced natural selection.

A method for detecting recent selection in the human genome from allele age estimates.

A method to test for recent selection by estimating the age of an allele from the extent of haplotype sharing at linked sites, indicating positive selection at HFE or a linked locus is developed.

Using linked markers to infer the age of a mutation

Two approaches for estimating allele age using variation at linked genetic markers are reviewed, with phylogenetic methods best suited for studies of ancient mutations, while population genetic methods are better suited for Studies of recent mutations.

An estimator of first coalescent time reveals selection on young variants and large heterogeneity in rare allele ages among human populations

Predictions that singleton alleles that alter proteins are significantly younger than those that do not, with a greater difference in the larger UK10K dataset, are confirmed.

The use of intraallelic variability for testing neutrality and estimating population growth rate.

It is concluded that the Delta32 allele at CCR5 and a disease-associated allele at MLH1 arose recently and have been subject to strong selection.

Precision and accuracy of divergence time estimates from STR and SNPSTR variation.

Divergence time estimates based on STR variation on the background of a derived SNP allele background are more accurate and more precise than STR-based estimates, conditional on a recent SNP mutation, and the combination of estimates based separately on STR and SNPSTR variation provides insight into the age of the derived SNP alleles.

A Bayesian method for jointly estimating allele age and selection intensity.

The problem of jointly estimating the intensity of past selection affecting an allele and the allele's age is formulated in a Bayesian framework and an importance sampling method applicable to low-frequency alleles is developed.

Estimating Time to the Common Ancestor for a Beneficial Allele

Using the method, population-specific patterns in the 1000 Genomes Project data are analyzed to provide a global perspective on the timing of adaptation for several variants which show evidence of recent selection and functional relevance to diet, skin pigmentation, and morphology in humans.

Recurrent mutation in the ancestry of a rare variant

This work develops a sampling theory for the number of latent mutations in the ancestry of a rare variant, specifically a variant observed in relatively small count in a large sample, and develops a Poisson sampling model for populations of varying size.

Estimating the age of alleles by use of intraallelic variability.

The results support the hypothesis that deltaF508 arose < 500 generations (approximately 10,000 years) ago and indicate that G542X is somewhat older than DeltaF508, for which intraallelic variability at three intronic microsatellite loci has been examined.

Two classes of methods for estimating the age of mutant allele at the disease locus based on linked marker data are proposed based on data collected from several European populations and from the Finnish population.

Likelihood analysis of disequilibrium mapping, and related problems.

It is concluded that the extent of linkage disequilibrium can lead to relatively accurate estimates of recombination and mutation rates and that those estimates are not very sensitive to parameters, such as the population age, whose values are not known with certainty.

Assessment of linkage disequilibrium by the decay of haplotype sharing, with application to fine-scale genetic mapping.

A powerful likelihood method for the analysis of linkage disequilibrium between trait loci and one or more polymorphic marker loci.

Using rare mutations to estimate population divergence times: a maximum likelihood approach.

A method to estimate by maximum likelihood the divergence time between two populations, specifically designed for the analysis of nonrecurrent rare mutations, which seems more suitable for large sample sizes and few alleles, whereas the RDc estimator appears preferable when this is not the case.

Disequilibrium mapping: composite likelihood for pairwise disequilibrium.

A Composite Likelihood (CL) model is proposed that has these features when the physical distances between the marker loci are known or can be approximated, and it is shown how the model can be generalized to account for multiple disease mutations.
