How We Rate Genetic Conditions

YES — Strong genetic cause; heritability >60%
PARTIAL — Genetics is one factor among several
COMPLEX — Many genes, many environmental factors
NO — Not primarily genetic in origin

All heritability estimates are drawn from peer-reviewed research via MedlinePlus Genetics, the CDC, and the NIH. 247GeneticCheck does not provide medical advice.
