Description

The p.C76S variant (also known as c.226T>A), located in coding exon 3 of the CFTR gene, results from a T to A substitution at nucleotide position 226. The cysteine at codon 76 is replaced by serine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. 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.
