TNFSF12 and telomere syndrome: As shown in Figures 7C–L, subsequent K-M survival analysis assessed the prognostic value of the identified key genes: ANGPTL1, APBB1IP, IFI6, MEDAG, NXPH3, RASL12, and TNFSF12 were positively associated with improved prognosis of STS, while elevated PERP and TROAP were associated with poor STS’s prognosis (p < 0.05).
