Clinical exome (WES) – blood relatives
DNA testing of relatives using exome sequencing method to determine causal variants responsible for patient phenotype (duo/trio analysis).
Material:
Peripheral blood, Buccal swab …Turnover Time:
6 monthsSTATIM
1 monthCascade testing for GJB2 gene mutation (for Connexin 26) – early non-syndromic AR deafness
Testing for GJB2 gene mutations (gap junction beta 2) responsible for hereditary autosomal recessive disease, early non-syndromic disorder/hearing loss and deafness, also referred to as DFNB1.
Material:
Peripheral blood, Buccal swab …Turnover Time:
3 weeksSTATIM
1 weekAR 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, Buccal swab …Turnover Time:

3 daysCystic 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 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.
