ALLELIC DETERMINATION
First Claim
1. A method of determining an allelic type of a specific individual, comprising:
- accessing a database of genetic information on a plurality of individuals, the genetic information comprising;
the allelic type of each individual; and
the type of each of a plurality of genetic markers for each individual;
categorizing the data in the database into a plurality of groups of individuals, such that all individuals having the same allelic type are in the same group, and each group represents a different allelic type;
inputting data comprising the type of each of a plurality of genetic markers of the specific individual having an unknown allelic type;
specifying a set of genetic markers for which type information is known both for the individuals in the database and for the specific individual;
applying a population genetic model to calculate the likelihood of sampling, from some or all of the groups in turn, the input type data of the specified set of genetic markers for the specific individual; and
determining the allelic type of the specific individual based on the calculated likelihoods.

A method of determining an allelic type of a specific individual, comprising: accessing a database of genetic information on a plurality of individuals, the genetic information comprising: the allelic type of each individual; and the type of each of a plurality of genetic markers for each individual; categorizing the data in the database into a plurality of groups of individuals, such that all individuals having the same allelic type are in the same group, and each group represents a different allelic type; inputting data comprising the type of each of a plurality of genetic markers of the specific individual having an unknown allelic type; specifying a set of genetic markers for which type information is known both for the individuals in the database and for the specific individual; applying a population genetic model to calculate the likelihood of sampling, from some or all of the groups in turn, the input type data of the specified set of genetic markers for the specific individual; and determining the allelic type of the specific individual based on the calculated likelihoods.

7. A method of selecting a set of genetic markers for use in determining an allelic type of a specific individual, the method comprising:
-
accessing a database of genetic information on a plurality of individuals, the genetic information comprising;
the allelic type of each individual; and
the type of each of a plurality of genetic markers for each individual;initialising to define a current set of genetic markers; determining the allelic type of each individual in the database using the current set of genetic markers; measuring the performance of the current set of markers by calculating a predetermined performance measure on the basis of the allelic types found in the determining step and the actual allelic types known from the database; keeping as the current set of markers the set that gives the best measured performance seen so far for a set of a given size; modifying the current set of markers; repeating the determining, measuring, keeping and modifying steps; terminating when a predetermined condition is met; and outputting the set of markers that gives the best measured performance seen as the selected set of genetic markers for use in determining an allelic type of an individual. - View Dependent Claims (10, 13)
