Ras gene is frequently mutated in cancer. Among different subtypes of Ras gene, K-Ras mutation occurs in nearly 30 % of human cancers. K-Ras mutation, specifically K-Ras (G12D) mutation is prevalent in cancers like lung, colon and pancreatic cancer.

DICER1-associated sarcoma is an emerging entity, defined by either somatic or germline dicer 1, ribonuclease III (DICER1) mutations and sharing characteristic morphologic features irrespective of the site of origin. In addition to the DICER1 driver mutation, concurrent genomic alterations, including tumor protein 53 (TP53) inactivation and RAS pathway activation, are frequently detected. Tumors that morphologically resemble malignant peripheral nerve sheath tumor (MPNST) have rarely been reported among DICER1 sarcomas and often pose diagnostic challenges.

Intrachromosomal amplification of chromosome 21 (iAMP21) B-cell precursor acute lymphoblastic leukemia (BCP-ALL) in children is a high-risk subtype for which targeted drugs are lacking. In this study, we determined the frequency of secondary lesions in 28 iAMP21 BCP-ALL patient samples and investigated cellular sensitivity for candidate-targeted drugs. iAMP21 was enriched in aberrations (10.

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas and the primary cause of mortality in patients with neurofibromatosis type 1 (NF1). These malignancies develop within preexisting benign lesions called plexiform neurofibromas (PNs). PNs are solely driven by biallelic loss eliciting RAS pathway activation, and they respond favorably to MEK inhibitor therapy.

The presence of specific genetic mutations in patients with glioblastoma multiforme (GBM) is associated with improved survival outcomes. Disruption of the DNA damage response (DDR) pathway in tumor cells enhances the effectiveness of radiotherapy drugs, while increased mutational burden following tumor cell damage also facilitates the efficacy of immunotherapy. The ATRX gene, located on chromosome X, plays a crucial role in DDR.
