Pedigree Prism™ is a new software product for creating accurate family pedigree diagrams, or genograms, for mammalian biological relationships. A pedigree is a fundamental bioinformatics research tool used by geneticists, clinicians and other medical personnel to display and communicate complex family relationships and display the associated genetic and clinical characteristics of individuals. The resulting family history diagrams can be used to exhibit patterns of heredity, including diseases, in families and populations. Pedigree Prism™ will offer medical researchers the ability to quickly and easily create and edit views of family pedigrees by importing data files or drawing relationships directly. This new product incorporates pedigree symbols and nomenclature that conform to current scientific standards. Affection status of individuals (the presence or absence of disease) can be displayed in four colors. Any number of clinical, genotypic or phenotypic attributes may be added to each individual record. Data may be imported and exported in tabular form. The pedigree display may be adjusted for size and position as desired and may be saved directly from the application for presentation. There will be a User Guide that will be internal to the downloaded Pedigree Prism™ application file.
