Single Gene Testing


CeGaT offers comprehensive laboratory diagnostics expertise, with more than 700 different single gene sequence analyses available. Furthermore, for many of these genes (> 350) we can also carry out further analysis using MLPA or quantitative PCR to detect deletions or duplications.

As more and more diseases are able to be diagnosed, we are constantly expanding the range of diagnostics we offer. We are happy to establish new analyses for you.

Sanger Sequencing
Sanger sequencing is particularly useful for small-scale applications, such as single gene testing. After amplification of the DNA coding segments and adjacent regions via PCR, sequencing is performed using a 96-capillary 3730xl DNA Analyzer from Applied Biosystems.

Analysis of Deletions and Duplications
For the detection of deletions and duplications we use MLPA ( or quantitative PCR. Quantitative PCR is carried out on the Quant Studio 12K Flex Real-Time PCR System from Applied Biosystems.

Fragment Length Analysis
Another service we offer is fragment length analysis by capillary electrophoresis. This method is used for disorders such as triplet repeat diseases. The gene regions of interest are amplified by unique primers, and the number of triplet repeats can be determined by analyzing the fragment lengths of the resulting PCR products. Fragment length is determined using the 96-capillary 3730xl DNA Analyzer by Applied Biosystems.
