Three independent studies from the UK, China, and the USA have reported that a GHR-P495T single-nucleotide polymorphism (SNP) in the GHR gene, resulting in an amino acid change at peptide position 495 from proline to threonine, is associated with a markedly higher odds ratio for NSCLC [15,16,17]. Here, GHR is linked to non-small cell lung carcinoma.
