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.
Material:
Peripheral blood, Isolated DNA from bloodTurnover Time:
3 weeksSTATIM
3 daysSpinal muscular atrophy – determination of copy number of exon 7 and 8 in the SMN1 gene
Examination of SMN1 and SMN2 genes associated with spinal muscular atrophy (SMA) by MLPA method. This concerns an autosomal recessive disease that is most often associated with homozygous deletion of exon 7 in the SMN1 gene (almost 95% of all patients with SMA).
Material:
Peripheral blood, Isolated DNA from bloodTurnover Time:
3 weeksSTATIM
3 daysAR deafness – detection of 35delG GJB2 mutation
Testing for 35delG mutation in the GJB2 gene responsible for AR hereditary, non-syndromic disorder/hearing loss (deafness).
Material:
Peripheral blood, Isolated DNA from bloodTurnover Time:
3 weeksSTATIM
3 daysResponse to hormonal stimulation – Ser680Asn polymorphism in the FSHR 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
3 daysPGT-M direct embryo sequencing
Testing for the presence of a known mutation in an embryo originating from one parent using (Sanger) sequencing of a specific region. Can only be done in conjunction with the PGT-M karyomapping method.
Material:
Trophectoderm, Amplified DNA from the trophectodermTurnover Time:
4 weeksSTATIM
2 weeksCascade 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.
