28 ABCC7 p.Trp1282* ABCC7 p.Arg553* ABCC7 p.Asn1303Lys ABCC7 p.Gly542* If IRT is elevated (N99th percentile) a screening test with the seven most common CFTR mutations in Switzerland (F508del, 3905insT, G542X, R553X, W1282X, 1717-1 GNA, N1303K) [12] will be used to confirm the suspicion. Login to comment 46 ABCC7 p.Trp1282* ABCC7 p.Arg553* ABCC7 p.Asn1303Lys ABCC7 p.Gly542* In brief, this assay is based on DNA amplification of four fragments containing the mutations (F508del, 3905insT, G542X, R553X, W1282X, 1717-1 GNA, and N1303K) by PCR, followed by hybridization with short, allele-specific oligonucleotide probes labeled with europium, terbium, or samarium chelates. Login to comment 63 ABCC7 p.Arg31Cys This child was diagnosed with atypical CF in the first week of life using molecular diagnostics (F508 del/R31C) as both parents were known heterozygous CF carriers.
