Here, we present the first case of peripheral T cell lymphoma with CSF3R variant that developed persistent neutropenia in the follow-up visit and aplastic anemia after autologous hematopoietic stem cell transplantation. Next-generation sequencing (NGS) was performed on bone marrow aspiration (Qiagen clinical insight-QCI (TM)). CSF3R single nucleotide variant (transcript variant 4), 46.0% (of 1081 reads) of variant allele fraction on exon 16 (lying to intronic region), nucleotide NM_172313.3, g36932463A > g, c.2041-35 T > C was identified by NGS. The case study presented here is an example of use of NGS in diagnosis, classification, prognostic or response indicator of hematologic malignancies, and identification of targeted therapy options in clinical practice. Additional work is needed to understand the clinical significance of this mutation.en10.1007/s12308-022-00513-8info:eu-repo/semantics/openAccessCSF3RPeripheral T Cell LymphomaFebrile NeutropeniaAplastic AnemiaMutationsOrganizationArticle154245248Q4WOS:0008504054000012-s2.0-85137499284Q3
