Resumen :
Introducción. La leucemia mieloide aguda (LMA) es un trastorno clonal neoplásico de células mieloides cuya clínica se debe a la insuficiencia medular. Las nuevas clasificaciones de la LMA otorgan mayor importancia a las mutaciones genéticas tanto para su clasificación como para la estratificación d...  Ver más
Introduction. Acute myeloid leukaemia (AML) is a neoplastic clonal disorder of myeloid cells whose clinical manifestations are due to marrow failure. New classifications of AML give increased importance to genetic mutations for both classification and risk stratification. Some germline mutations, such as DDX41, predispose to its development, although their prevalence and clinical features are not clearly defined. Objectives. To determine the prevalence of the DDX41 gene mutation in patients diagnosed with AML and the clinical and prognostic features of AML with germline mutation in DDX41. To compare with the casuistry of patients diagnosed with AML at the Hospital General Universitario Dr. Balmis in Alicante. Materials and methods. A bibliographic search was carried out using PubMed and Scopus on AML with germline mutation in DDX41. The prevalence and OS of patients diagnosed with AML with available sequencing study at the Hospital General Universitario Dr. Balmis in Alicante was studied. Results. In the literature, the prevalence of germline mutations in DDX41 in patients with MDS/AML ranges from 0.57% to 5.09%. The median age at diagnosis ranges between 61 and 72 years, with a male predominance of between 56% and 79.4% and normal cytogenetics. Regarding the casuistry of the Hospital General Universitario Dr. Balmis in Alicante, the prevalence is 1.03% and the median OS is 19.5 months (95% CI: 14-NA) in patients diagnosed with AML. Conclusion. The prevalence of germline DDX41 mutation ranges from 0.5% to 5% of AML. AML with germline DDX41 mutation usually occurs in males, older, with generally normal cytogenetics, with a somatic DDX41 mutation associated with the germline mutation, which is usually P/LP. The higher median OS of AML with germline P/LP mutation in DDX41 indicates a favourable prognosis. The OS of the sample from the Hospital General Universitario Dr. Balmis in Alicante is similar to AML not mutated in DDX41.
