Drawing a pedigree is a prerequisite in genetic counseling. In medical records, a pedigree is useful to document the family history of the patient. Drawing a pedigree is also necessary in collecting genetic resources for medical research such as positional cloning. Currently, most pedigrees are drawn by hand or by drawing software. Due to the special requirements in a standardized pedigree, generating a pedigree by these methods is usually time-consuming and requires professionals. This limits the usage of a pedigree as demanded in remote diagnosis or online counseling from the counselees to send an electronic pedigree.


We developed an online pedigree drawing tool, PediDraw, which enables users to generate pedigrees after inputting the family information step-by-step on web. It outputs a pedigree or table to present a family history to the counselors.


PediDraw is a user-friendly web-based drawing tool. It is accessible via Internet.
