Detection of aberrations by FISH
Genetic testing to specify structural chromosomal aberrations or to accurately quantify mosaicism in a sample.
Material:
Peripheral bloodTurnover Time:
4 weeksSTATIM
1 weekCystic 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.
Material:
Peripheral blood, Isolated DNA from bloodTurnover Time:
3 weeksSTATIM
1 weekMicrodeletion 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 bloodTurnover Time:
3 weSTATIM
1 weekResponse to hormonal stimulation – Ser680Asn polymorphism in the FSHR gene
Testing for p.Ser680Asn polymorphism in the FSH receptor gene (FSHR) by real-time PCR. This is aimed at investigating the Ser680Asn to Ser680Ser change that is associated with low sensitivity of FSHr to gonadotropins.
Material:
Peripheral blood, Isolated DNA from bloodTurnover Time:
3 weeksSTATIM
1 weekPredictive testing of known familial gene mutation from CarrierTest
Testing for carriage of familial pathogenic mutations detected during testing in the CarrierTest panel NGS test.
Material:
Peripheral blood, Buccal swab …Turnover Time:
3 weeksSTATIM
1 weekPredictive testing – a partner carries the gene mutation from CarrierTest but not tested in GNTlabs
CarrierTest is a panel NGS test of selected regions using data from exome libraries.
When to use this test: The partner is already a known carrier of a mutation in the gene that is included in the CarrierTest, so the patient is indicated to be tested for all mutations in the gene, which will also be performed by CarrierTest, but the partner has not been tested in our laboratory and compatibility will not be tested.
