摘要
Methods and systems of ranking a plurality of possible genetic conditions of a target subject related to assessed phenotypes of this subject comprise respective databases and search steps to provide the ranking. The genome of the target subject is analyzed, encrypted and changes are identified without providing user access to the changes. A database comprising genetic conditions linked at least in part to at least one relevant region in the genome of the subject and at least in part to at least one phenotypic characteristic. This database is searched based on the assessed phenotypes thereby providing a first ranking of possible genetic conditions, each genetic condition being related to at least one genetic change indicative of that condition. Weight scores are assigned to each of the identified changes based on predetermined criteria in order to adjust the first ranking and provide a second ranking of possible genetic conditions. A subjects database of other subjects comprises for each other subject, one or more phenotypic characteristics and the encrypted genome, wherein genetic changes in at least one relevant region in the encrypted genome are indicative of a possible genetic condition or conditions. The subjects database is searched for both phenotypic similarity and similarity of the genetic changes by respectively comparing the assessed phenotypes and the changes in the encrypted genome against the data in the subjects database. The target subject is respectively matched with one or more of the other subjects based on the phenotypic similarity therebetween and on the similarity of the genetic changes therebetween respectively. The matches are respectively ranked based on their respective degree of similarity. Depending on which set of matches was ranked first the other set will adjust the first ranking to provide a second ranking of possible genetic conditions since a given match in the second ranking is indicative of the possibility that the target subject shares the same genetic condition or conditions with the matched other subject.
