Description

The p.P1050T variant (also known as c.3148C>A), located in coding exon 20 of the CFTR gene, results from a C to A substitution at nucleotide position 3148. The proline at codon 1050 is replaced by threonine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
