Connective tissue is the sustaining tissue of all organs. For this reason, hereditary connective tissue diseases can manifest themselves differently. They centrally affect the blood vessels and the joints. Therefore, genetic analysis is crucial for clarifying a possible vascular involvement and is thus important for further clinical decisions. Since hereditary connective tissue diseases are often difficult to distinguish phenotypically, the gene set for connective tissue diseases is ideally suited to confirm the diagnosis for your patients. In addition to Cutis laxa and Ehlers-Danlos syndrome, this gene set also clarifies other hereditary connective tissue diseases such as Marfan syndrome and Loeys-Dietz syndrome and genetic causes of thoracic aortic aneurysms.
The Diagnostic Panel for Connective Tissue Diseases comprises 60 genes and is based on our proprietary, high-quality ExomeXtra® enrichment, covering all protein-coding regions as well as intronic and intergenic variants described as disease-relevant in the databases HGMD and ClinVar. In addition, the ExomeXtra® enrichment enables a genome-wide CNV calling with similar performance to array CGH. It thus provides the ideal basis for genetic diagnostics.

What We Offer with the Panel for Connective Tissue Diseases
Our Promise to You
Your Benefits
It is possible to request single or multiple predefined gene sets. In addition to the complete analysis of the genes of the requested gene set, we extend the analysis by additional genes for differential diagnosis. We report variants of unknown significance (ACMG class 3) and pathogenic and probably pathogenic variants (ACMG classes 4 and 5) for the primarily ordered gene set. For the genes included due to differential diagnosis, we restrict the reporting to pathogenic and probably pathogenic variants (ACMG classes 4 and 5), which could be related to the indication of the person seeking advice.
The Diagnostic Panel for Connective Tissue Diseases is based on CeGaT’s ExomeXtra® enrichment. This allows, without additional sequencing, phenotypically eligible gene sets of other CeGaT panels or single genes to be additionally ordered. If you would like to assemble an individual panel, please feel free to contact us. We will be happy to support you.
In addition to the primary diagnostic assignment, the assessment of ACMG genes and pharmacogenetic profiling may also be ordered.
Method
The enrichment of the coding regions and the adjacent intronic regions is performed using an in-solution hybridization technology. The selection of the targeted regions and the design of the enrichment baits is performed in-house. High-throughput sequencing is performed on our Illumina platforms. Bioinformatic processing of the data is achieved using an in-house computer cluster.
Following data processing, our team of scientists and specialists in human genetics analyze the data and issue a medical report.

ACMG Genes
Genetic variation may sometimes be identified, which does not fit within the scope of the requested genetic analysis (so-called secondary findings). The reporting of these variants is limited to pathogenic alterations (ACMG classes 4 and 5) within selected genes, for which a treatment or course of action exists for you or your family (according to the current guidelines of the American College of Medical Genetics and Genomics). Details on genes and associated diseases can be found here.
Pharmacogenetics
Pharmacogenetic analysis detects genetic changes that affect the effectiveness of drugs. Genetic variants that affect proteins responsible for the metabolism of substances can significantly change their tolerance and efficacy. These drugs include, among others, antidepressants, pain relievers, neuroleptics, chemotherapeutics, AIDS drugs, thrombosis drugs, anesthetics, beta-blockers, or statins.
The reduced activity of a specific enzyme can lead to an increased drug level in the standard dosage, which is often associated with undesirable side effects. With drugs that are only activated by metabolism, the therapeutic effect can be completely absent. Likewise, due to the resulting increased rate of degradation of the medicinal substance, an increased enzyme activity leads to inadequate effectiveness of the therapy.
The pharmacogenetics option analyzes known variants in twenty-two genes involved in the metabolism of drugs. If specific gene variants occur, the treating doctor can adapt the therapy individually. The pharmacogenetic analysis can minimize serious side effects and helps to avoid failure of the treatment.
