TNIP1 and myelodysplastic syndrome: Abin1 is located on chromosome 5q in the region commonly deleted in 5q– syndrome, the most distinct of all MDSs.[8a] The expression of Abin1 in mononuclear BM cells of patients with del(5q) MDS is lower than that in patients with non‐del(5q).[15] To further determine the correlation between Abin1 and MDSs, we reanalyzed publicly available datasets of primary BM CD34+ cells from patients with del(5q) MDS.[16] The Abin1 mRNA levels were significantly lower in the patient samples than in those from healthy individuals (Figure S1a, Supporting Information).
