Rheumatoid? So the doctor's an idiot and doesn't want to change (the first part of the word), and patient with him is just sick (the second part of the word)

Prognostic testing is one form of genetic testing. Also known as predictive testing. These types of testing used to detect gene mutations associated with disorders that appear after birth, often later in life. These tests can be useful to people who have a family member* genetic disorder, but who have no obvious signs of the disease during testing. Predictive testing can identify mutations that increase the risk of developing disorders of a person with a genetic basis, for example, certain types of cancer . Women with a pathogenic mutation in BRCA1 have a 65% cumulative risk of breast cancer**. Predictive testing can determine whether a person develop a genetic disorder such as hemochromatosis (leads to accumulation of iron in organs), before the appearance of any signs or symptoms. The results of a prediction and predictive testing can provide information about the risk of a person to develop certain diseases, help in making decisions about medical care.

*Known or famous member of the family (in any generation). Not everyone knows their relatives. Not all family members are carriers live to see the manifestation of hereditary diseases. Medical records is a relatively new invention, in Russia it is not accepted to advertise their disease, the most severe whisper, so they remain unknown even to relatives. Men don't cry and don't complain. Ashamed to go to the doctor, and psychologist. This psychology leaves family in danger. For such a case on sites of orphan diseases have templates of letters to his relatives. Abroad, there are precedents of claims of the clinic to the patient to prevent the death of children.

Researchers and experts, such as Dr. Michael Vincent and Dr. Michael Ackerman have long relied on family history to help in the diagnosis of inherited cardiac arrhythmias. Collecting detailed medical histories from patients largely helped to open the the first chromosomal locations of genes causing an abnormally long QT interval.

[...]

Your family pedigree can identify other family members who may be at risk, but don't know it. They should be tested with ECG and genetic testing, to be treated to prevent a tragic death.
