A method for assessing susceptibility of a subject to a genetically related disease or condition relative to a general population. The method includes the steps of: determining the presence or absence of a plurality of risk factors associated with the subject and having a correlation with the disease or condition; assigning a risk score, to each of the selected risk factors determined to be present, based upon a strength of correlation assigned to the factor with respect to the disease or condition; and combining the risk scores to calculate an overall susceptibility score, wherein the overall susceptibility score represents susceptibility of the subject to the disease or condition in relation to a base score representing the risk that a member of the general population will have the disease or condition without consideration of risk factors. The risk factors require the inclusion of at least two of age, gender, race, and family history and require the inclusion of a plurality of polymorphisms selected for known correlation with the disease or condition.
