Focus on clinical utility

Since the discovery of the CFTR gene in 1989, more than 1900 mutations and variants have been described as causative for cystic fibrosis (CF). Many of these mutations are ‘private’, having been described only in one patient and/or family. Routine testing for all possible mutations is neither feasible nor cost effective and is therefore confined to testing for the most common mutations.

CF-EU2 is the only commercially available pan- European CF testing kit designed specifically to address the most common mutations found across populations of European origin. Alongside this assay, Yourgene Health offer a number of population-specific bolt-on panels, as well as bespoke offerings for national programs. The assay is designed with all clinically relevant diagnostic scenarios in mind, including newborn screening and male factor infertility testing.

The CF-EU2 assay identifies 50 mutations in total, and also analyses the intron 8 polyT tract with accurate measurement of the adjacent TG repeat. The polyT tract at the junction of intron 8 and exon 9 influences transcription. Specifically, the number of thymidine residues (5T, 7T or 9T) affects the splicing efficiency of exon 9. If the 5T allele is present, a proportion of exon 9 transcripts will be absent resulting in non-functional protein and variable CF symptoms. It is reported that the number of TG repeats upstream of the polythymidine tract can also influence splicing of exon 9. If present on the same allele as the 5T variant (cis) the larger the number of TG repeats, the higher the proportion of CFTR transcripts will lack exon 9. The CF range is unique amongst commercially available assays in its ability to accurately identify the number of TG repeats in addition to polyT status.


Flexibility and simplicity from sample to report

The CF range is compatible with most commonly employed DNA extraction protocols, thermal cyclers and capillary electrophoresis instruments. This flexibility in approach is complemented by simple and easy to use analysis software for reporting. Results can be analysed through either Life Technologies GeneMapper or SoftGenetics GeneMarker software.
