WebApr 21, 2024 · GATA1 mutations have been linked to congenital dyserythropoietic anemia and fall into 2 main classes: (1) splicing or start codon mutations leading to expression of a shorter GATA1 protein (GATA1s) starting at amino acid 84, or (2) mutations in the first ZnF domain, disrupting interactions with cofactors (see figure). WebGATA1 is expressed in primitive and definitive erythroid cells (27, 55), megakaryocytes (61, 92), eosinophils (138), and mast cells (61) and in the Sertoli cells of the testis (46, 131).
