CAP FAD NUMBERS
FAD numbers are assigned to each individual in the CAP project. The numbers are 5 digits and are used to identify each individual by Family Identification Number, sex, birth order, and adopted or control status. The following table shows the correct number assignments.
Here is a Printable Table. If you need a more thorough understanding, please study the table below and then proceed to the exercise.

| 1-3 | Family Identification Number | Assigned at Entry. For each 3 digit number there are 2 families, an adopted group and a control group. These numbers begin at 001 and go through 907, although there are no numbers in the 800s. There are also several bfad numbers which begin at 950. These were assigned to siblings who were adopted into already participating families. Individuals with 950+ numbers have 2 FADNUMs. One that relates to the original family number and a separate 950+ number (or BFADNUM) that identifies them as proband status participants. | ||
