Key Pharmacogenomic Note: KRAS mutation status (especially codon 12/13 mutations) is a critical biomarker for anti-EGFR therapy resistance in colorectal cancer. Patients with KRAS-mutant tumors do not respond to cetuximab or panitumumab.

Reference compiled from: HGNC, Ensembl, NCBI, UniProt, PDB, AlphaFold, ClinVar, AlphaMissense, SpliceAI, Reactome, Gene Ontology, STRING, BioGRID, IntAct, SIGNOR, CollecTRI, ChEMBL, PharmGKB, Bgee, OMIM, GenCC, Orphanet, HPO, GWAS Catalog I’ve compiled a comprehensive cross-database identifier and functional mapping reference for human KRAS. This document covers all 12 requested sections with data sourced from over 20 biological databases. Key Highlights:

  • 462 PDB structures - one of the most structurally characterized proteins, reflecting intense drug development efforts
  • 2 FDA-approved KRAS-targeting drugs - Sotorasib (AMG 510) and Adagrasib (MRTX849), both covalent G12C inhibitors
  • 565 ClinVar variants with 37 classified as pathogenic (hotspots at G12, G13, Q61)
  • 10,098 protein-protein interactions in STRING, with key effectors RAF1, BRAF, and PI3K
  • 71 Reactome pathways spanning RAS/MAPK signaling, receptor tyrosine kinase cascades, and disease-specific pathways
  • Ubiquitous expression across 298 tissues with highest in trigeminal ganglion, GI mucosa, and epithelia
  • Strong disease associations with Noonan syndrome 3, CFC syndrome 2, and multiple cancers This reference serves as a definitive lookup resource linking KRAS across genomic, transcriptomic, proteomic, structural, pharmacological, and clinical databases.
