However, for LUSC cases, we observed the 4% alteration rate with the type of “missense mutation,” “amplification,” and “deep deletion” (Figure 3C), and the correlation between the genetic alteration of SNRPA and the worse OS prognosis (Figure 3D, p = 0.016), suggesting the potential involvement of SNRPA genetic alteration in the clinical prognosis of lung squamous cell carcinoma. Here, SNRPA is linked to squamous cell lung carcinoma.
