Core Tip

Core tip: Genetic analysis of the transmembrane conductance regulatory (CFTR) gene is helpful to characterize patients with cystic fibrosis, but sequencing and multiplex ligation-dependent probe amplification-based testing are only done to diagnose rare or unknown variants. Here we report a 16-year-old boy, the son of consanguineous healthy parents, who lacked both the normal and mutant forms of the ∆F508 alleles in initial molecular tests. Further analysis disclosed a rare large homozygous CFTR gene deletion in this patient.
