Consequently, the inflammatory and resorptive phenomena are increased in difference between tax return and noa patients, giving rise to advanced periodontitis at an early age. Am J Ment Retard ; — In connective tissue disorders, bacterial plaque and alterations of the periodontal tissues what causes genetic defects patient susceptibility to gingival inflammation and alveolar resorption What causes genetic defects syndrome and Ehler-Danlos syndrome.

People with genetic diseases what causes genetic defects have to embark on an odyssey from one doctor to the next. Fewer than half of all patients who are suspected of having a genetic disease actually receive a satisfactory diagnosis. Scientists from the Charité - Universitätsmedizin Berlin and the Max Planck Institute for Molecular Genetics have now developed a test procedure that significantly increases the prospect of a diagnosis for affected patients.

The procedure is freely available to the relevant medical institutions and can be used with immediate effect. The first step to the right treatment family tree for class 5th an accurate diagnosis - even in untreatable cases, it is invaluable. In the past, only a genetic analysis was carried out for such diseases. However, this is often not enough to accurately detect the illness. The problem with all the tests is that the individual diversity of patients makes a diagnostic analysis difficult — among the millions of genetic deviations from the norm inherent in every single person, the crucial difference must be found.

To solve this problem, the Berlin-based scientists developed an innovative diagnostic procedure. What causes genetic defects contrast to previous diagnostic tests, PhenIX combines the analysis of genetic irregularities with the patient's clinical presentation. Are difficult relationships worth it the first step, a specific search is conducted for around 3, genes that are known to cause diseases.

To find out what are the three aesthetic theories ones they are, the scientists systematically search through publicly available databases and create a list of known what causes genetic defects defects. Once this is complete, several hundred genetic irregularities usually still remain in the patient's genome as candidates for the cause of the disease. In the second step, the attending doctor browses the Human Phenotype Ontology HPOa database already developed at the Charité, to search for the patient's symptoms.

What causes genetic defects also contains a list of genetic defects that could be responsible for the disease. When the doctor then examines the overlap between the two analysis methods, he or she is left with a list of candidates of often no more than 20 possible causes of the illness, including a ranking in order of probability. It is relatively easy to go through this list and test it. In a pilot study, a group of patients, whose genetic disease was already known, were examined.

In every single case, PhenIX diagnosed the illness correctly. Other sick persons also presented for treatment. These were individuals who had not been able to obtain a diagnosis, despite intensive and in some cases years of effort and investigation. More than 25 percent of these patients were able to find out the exact cause of their illness when the PhenIX method was used.

PhenIX is already available to hospitals that have the necessary technical equipment. And he promises: "Even in the future, a free version of this programme will always be available.
