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 daysCascade 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.
Material:
Chorionic villi, Amniotic fluid …Turnover Time:
3 weeksSmith-Lemli-Opitz syndrome – detection of the 3 most common mutations in the DHCR7 gene (p.Trp151Ter, p.Val326Leu and c.964-1G>C)
Screening of the 3 most common DHCR7 gene mutations: c.452G>A (p.Trp151Ter), c.976G>T (p.Val326Leu), c.964-1G>C (IVS8-1G>C) using Sanger sequencing, which represent about 81% of all mutations in patients with SLOS (Smith-Lemli-Opitz syndrome, OMIM 270400).

1 weekCascade testing of the product of conception (by QF-PCR methods) excluding maternal contamination
Cascade aneuploidy testing of aborted foetal tissue using QF-PCR, arrays or karyotyping; excluding maternal contamination.
