NOTCH4 and myopericytoma: In our study, which employed the cBioPortal public database, EGFR mutations were determined to be significantly higher in the Chinese cohort as compared to the MSKCC cohort, ALK fusions were exclusively detected in the Chinese cohort, and KEAP1 and NOTCH4 mutations were only detected in the MSKCC_MPC cohort,and we suspect that NOTCH4 gene mutations may be a characteristic mutation unique to the MPC cohort of Western populations.
