Information processing system using base sequence relevant information

A method for processing information on nucleotide sequence comprising:

• (a) calculating a percentage for each piece of nucleotide sequence-related information using a first occurrence frequency and a second occurrence frequency, wherein the first occurrence frequency is calculated for each possible piece of nucleotide sequence-related information in a given position in a nucleotide sequence based on a predetermined population and the second occurrence frequency is calculated for each possible piece of nucleotide sequence-related information in the position based on the population gathered for predetermined individual-related information concerning an individual;
• (b) associating the percentage calculated in step (a) with positional information representing the position and with the nucleotide sequence-related information for each predetermined piece of individual-related information;
• (c) subjecting the percentage calculated in step (a) to relativization based on a predetermined standard value to obtain a relative value;
• (d) evaluating the correlation between the predetermined individual-related information and nucleotide sequence-related information in the position by comparing the relative value obtained in step (c) with a predetermined standard value;
• and
• (e) identifying another piece of individual-related information that had been determined to have a tendency of similar for a predetermined piece of individual-related information, which had been determined to have no correlation with nucleotide sequence-related information in step (d) and that had been determined to have correlation with nucleotide sequence-related information in step (d), and calculating an indicator for an indirect correlation between the predetermined individual-related information and nucleotide sequence-related information using a value indicating the tendency of similarity and a relative value concerning nucleotide sequence-related information that is correlated with the identified individual-related information.
