Cascade 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.

1 weekCystic 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.
