Diabetes Prediction

The DPF Function uses information from parents, grandparents, full and half siblings, full and half aunts and uncles and first cousins.

It provides a measure of the expected genetic influence of affected and unaffected relatives on the patient's eventual diabetes risk. It is calculated using:

$$DPF = {{\sum_{i}{K_i} (88-ADM_i) + 20} \over {\sum_{j}{K_j} (ALC_j - 14) + 50}}$$

*Where*
${K_x\quad}$ is the percent of genes shared by the ${relative_x}$ and
${\qquad}$${\qquad}$equals 0.500 when the ${relative_x}$ is a parent or full sibling
${\qquad}$${\qquad}$equals 0.250 when the ${relative_x}$ is a half sibling, grandparent, aunt or uncle, and
${\qquad}$${\qquad}$equals 0.125 when the ${relative_x}$ is a half aunt, half uncle or first cousin
${ADM_i\quad}$ is the age in years of ${relative_i}$ when diabetes was diagnosed
${ALC_j\quad}$ is the age in years of ${relative_j}$ at the last diabetic examination (prior to patient's examination)
