SMARCA4 and gastric cancer: Huang, S. C. et al. reported [29] that 2% (27/1199) with altered SMARCA4 expression were identified, exhibiting completely lost (N = 6), reduced (N = 9) or heterogeneous (N = 12) patterns, and seven SMARCA4 mutations were identified in seven cases, including three SMARCA4-lost gastric cancers harboring SMARCA4 gene alterations with p. K1091X, p. Y1076X, p. G775S, one SMARCA4-reduced gastric cancer harboring SMARCA4 gene alterations p. L796F, and three SMARCA4-heterogeneous gastric cancers harboring SMARCA4 gene alteration patterns with p. K540X, p. R397X and p.R1135W.
