They compare DNA sequences
of affected family members with those from healthy relatives, looking for unusual sequences in affected people that might turn out to be the defective genes.
Unlike other autoimmune disorders with associated risk factors, APECED is clearly caused by a mutation in a single gene, based on
analyses of affected families.
Studies have suggested that «genetic anticipation» — progressively earlier onset and increased severity of disease in successive
generations of affected families — is a feature of HPAH.
In UK studies, the likelihood of finding a mutation in this gene in melanoma families is much greater in families with larger

However, the government decided to deny funding to all of the participants other than the police, the criminal justice branch and a limited
number of affected families, making it difficult if not impossible for community groups to participate.
When seeking the genes at fault in a disease, they find all too often that the trail goes cold because there aren't enough members
of affected families or isolated groups of people to pin down the genetic risk factors.
While it is ideal to have
all of the affected family members present in the room, that is not always possible or practical.
