Determination of TPMT mutation status, allele *1, *2, *3A, *3B, *3C (mutations c.238G>C, c.460G>A and c.719A>G)
TPMT gene testing is performed by PCR and reverse hybridization strip assay to detect *1, *2, *3A, *3B, *3C alleles (c.238G>C, c.460G>A and c.719A>G mutations), which are responsible for the reduced activity of this enzyme catalyzing components of thiopurine drugs used in cancer therapy.
Material:
Peripheral blood, Buccal swab …Turnover Time:
3 weeksSTATIM
3 daysDetermination of NUDT15 gene mutation status, allele *1, *2, *3, *4, *5 (mutation c. 415C>T, c. 416 G>A and c.52G>A)
NUDT15 gene testing by real-time PCR is performed to detect NUDT15*1, NUDT15*2, NUDT15*3, NUDT15*4, and NUDT15*5 alleles (c. 415C>T, c. 416G>A, and c.52G>A), which are involved in the metabolism of thiopurine drugs.
Material:
Peripheral blood, Buccal swab …Turnover Time:
3 weeksSTATIM
1 weekHLA-C (C1/C2) Genotyping
HLA-C typing at the allelic resolution level is used for the detailed determination of HLA-C gene variants. This gene plays a crucial role in the communication between the mother's immune system and the developing embryo during pregnancy. HLA-C analysis helps identify specific combinations of maternal and fetal genes that may be associated with a higher risk of complications such as recurrent miscarriages, preeclampsia, intrauterine growth restriction (IUGR), or preterm birth. We recommend combining it with the KIR haplotype determination method.
Material:
Peripheral blood, Isolated DNA from bloodTurnover Time:
3 weeksSTATIM
2 weeksKIR (Killer-cell immunoglobulin-like receptor) haplotype evaluation
The KIR haplotype (A/B) determination method allows for the identification of the mother's genetic makeup in the region of KIR receptors. These receptors play a crucial role in the communication between the mother's immune system and the embryo during pregnancy, where they recognize HLA-C molecules on the embryo's surface. Analysis of the KIR haplotype can help reveal specific maternal genotypes that, in combination with the fetal HLA-C, may be associated with a higher risk of pregnancy complications.

2 weeksCystic 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, Buccal swab …Turnover 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).
