Next Generation Sequencing NGS
Searching for mutations in about 23 000 genes!
The human body is composed of proteins, which are made of a string of amino acids. The sequence of amino acids is saved in the DNA and more specifically in exones - sections responsible for coding (check the diagram). Usually proteins of all living organisms consist of 20 amino acids. DNA mutations may cause serious protein disorders which can be the source of a disease.
Genetic diagnosis (searching for mutations) for various diseases is based on diagnostic tests or the traditional sequencing method (so-called Sanger sequencing). Although these methods are really effective and common in medicine, they are most often used for analysing only one gene.
MedGen, as one of the first medical centers in Poland, has implemented for medical diagnostics NEXT GENERATION SEQUENCING - NGS. This technology allows to analyze all the genes at once which significantly reduces costs of a genetic test and increases the possibility of finding a pathogrenic mutation.
Out offer includes analysis of all exones (Whole Exome Sequencing) as well as specific gene groups.

The NGS test can be ordered by anyone even for preventive purposes (verification of mutation carrier)
The NGS test should be proposed to patients, in which genetic diagnostics carried out so far failed to give an answer – did not indentify any genetic defect responsible for the clinic problem, as well as in cases when the diagnostics assessed by the clinical genetics doctor will be very costly due to the complexity of the medical problem.
In out facility, range of the NGS test is always adjusted to the patient's cilinical symptoms, which is an essential element of the personalised medicine. You can find the full offer of NGS tests here.
