In November 2023, a study led by Professor XiaoFan Zhu from Chinese Academy of Medical Sciences Blood Disease Hospital (Institute of Hematology, Chinese Academy of Medical Sciences) was published in the international academic journal ——BMC Med Genomics. The title of the study is "Mutation spectrum, expression profiling, and prognosis evaluation of Fanconi anemia signaling pathway genes for 4259 patients with myelodysplastic syndromes or acute myeloid leukemia". The study sheds light on the complex interplay between Fanconi anemia (FA) signaling pathway genes and the pathogenesis of myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML).
Fanconi anemia (FA) is a rare genetic disorder associated with an increased risk of myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). Understanding the role of FA signaling pathway genes in the pathogenesis and prognosis of these hematological malignancies is crucial for improving patient outcomes. This study aims to elucidate the mutation spectrum, expression profiles, and prognostic implications of FA genes in MDS and AML, utilizing a comprehensive analysis of multiple patient cohorts. Through extensive bioinformatics and statistical analyses, including principal component analysis, correlation analysis, Kaplan-Meier survival analysis, and the development of predictive models, the study provides valuable insights into the role of FA genes in MDS and AML.
The study integrates data from 10 cohorts comprising 4259 patients with MDS or AML. Data from various cohorts, including SELF_FA, TCGA-LAML, and TARGET-AML, are utilized to assess FA gene expression and mutation patterns. Bioinformatics and statistical analyses are employed to explore FA gene mutations, expression patterns, and their correlation with clinical outcomes. Rigorous methodologies, including principal component analysis, correlation analysis, Kaplan-Meier survival analysis, and the development of predictive models for survival rates and cytogenetic risks, are employed to ensure robustness and reliability of the findings.
To comprehensively investigate the role of Fanconi anemia (FA) signaling pathway genes in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML), we employed a rigorous approach integrating data from multiple cohorts and employing various bioinformatics and statistical analyses.To evaluate the prognostic implications of FA gene alterations, we performed Kaplan-Meier survival analysis, stratifying patients based on FA mutation status and gene expression levels. This allowed us to determine the impact of FA gene alterations on overall survival and other clinical endpoints.
Furthermore, we developed predictive models for survival rates and cytogenetic risks using advanced statistical techniques. These models, including nomograms and classifiers, were constructed based on FA gene expression data and other clinical variables, providing clinicians with valuable tools for risk assessment and treatment planning.
Our analysis revealed a distinct mutation spectrum and altered expression profiles of FA genes in MDS and AML patients. Specifically, we observed a decrease in the expression of FNACD2, FANCI, and RAD51C in the FA mutation group, which correlated with a more favorable overall survival prognosis. These findings suggest that mutations in certain FA genes may confer a survival advantage in MDS and AML patients.
Additionally, we developed novel predictive models, including a nomogram for survival rate prediction and a classifier for cytogenetic risk assessment. These models were based on FA gene expression data and other clinical variables, offering clinicians valuable tools for personalized risk assessment and treatment planning. Overall, our results highlight the importance of FA signaling pathway genes in the pathogenesis and prognosis of MDS and AML, and provide clinicians with valuable tools for risk assessment and treatment optimization.

In conclusion, our study sheds light on the complex interplay between Fanconi anemia (FA) signaling pathway genes and the pathogenesis of myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). Through a comprehensive analysis of mutation spectrum, expression profiling, and prognostic evaluation, we have uncovered intriguing insights into the role of FA genes in these hematological malignancies.
Our findings indicate that mutations in certain FA genes may confer a survival advantage in MDS and AML patients, as evidenced by a more favorable overall survival prognosis in the FA mutation group. Conversely, high expression of specific FA genes was associated with poor overall survival, underscoring the complex and context-dependent nature of FA gene alterations in predicting clinical outcomes.
