Filter by name:

Fragile X syndrome – detection of CGG repeat expansion in the FMR1 gene

The testing is performed to determine the presence and extent of CGG triplet expansion in the IT15 region of the FMR1 gene.

Material:

Peripheral blood, Isolated DNA from blood

Turnover Time:

3 weeks

Cystic fibrosis – 50 mutations + Tn variants of IVS8 in the CFTR gene

Testing for the 50 most common CFTR gene mutations and determination of polymorphism in intron 8 (IVS8 Tn/TGn). These 50 mutations represent over 92% of the findings in patients diagnosed with CF in the Czech population using fragmentation analysis.

Microdeletion of Y chromosome – AZFa, AZFb, AZFc including SRY

Testing for microdeletions in the AZF (azoospermia factors) region of the Y chromosome (AZFa, AZFb, AZFc) by fragmentation analysis.

Material:

Peripheral blood, Isolated DNA from blood

Turnover Time:

Cascade prenatal testing (by QF-PCR, array) excluding maternal contamination

Cascade aneuploidy testing of material after invasive prenatal examination using QF-PCR and array methods, excluding maternal contamination. This can be supplemented by foetal karyotyping, if necessary.
