Avapritinib is an orally available, potent and highly selective inhibitor of KIT and PDGFRA
. Previously published preclinical results have shown that avapritinib has potent activity against KIT and PDGFRA
mutant kinases associated with GIST.
amplification is common in pediatric and adult high-grade astrocytomas and identifies a poor prognostic group in IDH1 mutant glioblastoma.
This is the reason why c-kit and PDGFRA
mutations are mutually exclusive.
In case of CD-117 negativity, the tumours require further testing with C-KIT mutations and PDGFRA

We excluded 10 reports because they failed to report immunohistochemical (IHC) staining for CD117 or failed to report the results of the analysis discovered on GIST-1 (DOG-1) or platelet-derived growth factor receptor alpha (PDGFRA
) markers for the CD117-negative tumors.

The genotype distribution comparison of 42 SNPs among 96 Slovenian healthy controls (SLO) and a European population (data for 503 individuals were obtained from the Ensembl database) revealed significant differences (P < 0.05) in distribution of genotypes in 10 SNPs: rs3024498 (IL10), rs315952 (IL1RN), rs2256965 (LST1), rs2256974 (LST1), rs909253 (LTA), rs2857602 (LTA), rs3138045 (NFKB1A), rs3138056 (NFKB1A), rs7656613 (PDGFRA
), and rs1891467 (TGFB2) (see Figures 1 and 2).
