Fig. 1 — Information entry screen of f-treeGC; information for three generations is required to create the pedigree (a). The genealogical information requested includes name (b, u), age (c, d), gender, general status [affected (i, j, k), asymptomatic/presymptomatic carrier, carrier, or deceased], infertility status, pregnancy status, fetal status, and disease status (m, n, o, p, q, t) of individuals belonging to three generations. In addition, client, proband and birth order information, including multiple gestation (e, f), custody (g), multiple individuals (h), donor or surrogate, adoption, and consanguinity (l) information may be inserted. The chart-creation process is visible for inspection on the lower left side of the f-treeGC screen in real time (r). A multiple-choice questionnaire for genetic information is filled out by an interviewer or the client; then, f-treeGC automatically creates a pedigree chart (r, s, t, v, w)
