The immunohistochemical results showed that the CIP group had lower VEGFA expression with a ratio of 80% to 40%, higher TNFRSF14 expression with a ratio of 60% to 10%, and higher TNFSF15 expression with a ratio of 30% to 10% (Figures 5B–D). Here, VEGFA is linked to hereditary sensory and autonomic neuropathy.
