STIM1 and anemia (phenotype): However, since thrombocytopenia and anemia are observed in some TAM patients caused by STIM1 mutations (Morin et al, 2020), as well as three different STIM1 TAM mouse models (Cordero-Sanchez et al, 2020; Grosse et al, 2007; Silva-Rojas et al, 2019), we conducted blood cell analyses and assessed clotting function in 8 M old WT and GS mice.
