Family History Risk Checker
Pick a condition, tell us how many close relatives have had it, and get a plain-language read on how much genetics is likely to matter for you — based on the same heritability data behind every page on this site.
Why family history matters differently for every condition
Not every condition is equally influenced by genetics — that's the whole point of the YES / PARTIAL / COMPLEX / NO verdict system used across this site. A condition rated YES (heritability above 60%, often single-gene) means a close relative's diagnosis is a much stronger signal than the same relative's diagnosis with a condition rated NO (not primarily genetic). This tool applies that same published heritability data to your specific family history answer instead of leaving you to interpret the percentage yourself.
Heritability data drawn from MedlinePlus Genetics, the CDC Genomics programme, and peer-reviewed research — the same sourcing used on every condition page on this site.

How does the family history risk checker work?
Pick a condition and tell us how many close relatives (parents, siblings, or children) have been diagnosed with it. We combine that with the condition's published heritability percentage and inheritance pattern to give you a plain-language read of how much family history typically matters for that specific condition — it is not a diagnosis or a personal risk score.
Is this tool a substitute for genetic counselling?
No. This tool gives general, condition-level information drawn from published heritability research — it cannot assess your individual genetic risk. If a condition runs in your family, a genetic counsellor or your doctor can order the right test and interpret the result properly.
Can a DNA test tell me my actual risk?
For many conditions, yes — an at-home DNA test such as CircleDNA's Premium Test can screen for relevant genetic variants across 500+ health reports. For conditions with a strong single-gene basis, or where a relative's diagnosis needs confirming, a clinical test such as those offered by HealthLabs or Paternity Lab may be more appropriate. Always discuss results with a healthcare professional.
