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, 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).
Material:
Peripheral blood, Buccal swab …Turnover Time:
3 weeksSTATIM
3 daysFragile 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, Buccal swab …Turnover Time:
3 weeksSTATIM
3 daysSmith-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).
Material:
Peripheral blood, Buccal swab …Turnover Time:
3 weeksSTATIM
1 weekHaemochromatosis – H63D, S65C, C282Y mutation in the HFE gene
HFE gene testing by real-time PCR is performed to detect the most common p.C282Y, p.H63D and p.S65C mutations associated with hereditary haemochromatosis.
Material:
Peripheral blood, Buccal swab …Turnover Time:
3 weeksSTATIM
3 daysAlpha-1-antitrypsin deficiency – PI*Z (p.Glu366Lys) and PI*S (p. Glu288Val) alleles in the SERPINA1 gene
SERPINA1 gene testing using Sanger sequencing is performed to detect PI*Z (p.Glu366Lys) and PI*S (p. Glu288Val) alleles.
