WebFeb 10, 2024 · Genetic testing finds the mutation causing FH in about 60-80% of people thought to have FH. Some mutations that cause FH remain unknown. This means that some people with FH will have a mutation that is not found through genetic testing. Finding a mutation is not required for diagnosing FH.
