rs1042077, also known as c.2562T>G, T2562G, and p.Thr854=, is a common synonymous polymorphism in the CFTR gene.

Since this particular nucleotide change does not change the amino acid at the corresponding codon of the cystic fibrosis protein, and is thus considered a 'silent mutation', the observation that cystic fibrosis patients seem to often have this variant has been puzzling.

Researchers in 2017 have published a finding that they feel explains how this silent change results in lowered amount of functional protein - the tRNA responsible for processing the variant codon is relatively rare in lung cells, leading to detrimental changes in protein stability and function. This may be a model for how other silent mutations affect protein function.[PMID 28510592OA-icon.png]
