Summary of "Somatic mutations in myelodysplastic syndrome with ring sideroblasts and chronic lymphocytic leukaemia."

SF3B1 is the largest subunit of the Spliceosome Factor 3b (SF3B) complex and part of the U2 small nuclear ribosomal protein. It functions as an important part of spliceosomal assembly, converting precursor messenger RNA (mRNA) to mRNA ready for ribosomal translation. Mutations of are commonly seen in myelodysplastic syndromes with ring sideroblasts (MDS-RS)and MDS/myeloproliferative neoplasm (MPN-RS-T). These mutations are typically heterozygous missense substitutions, of which, 55% involve K700E. MDS-RS and MDS/MPN-RS-T usually carry a more favourable prognosis than other subtypes of MDS. itself does not influence survival in these conditions, but does correlate with increased thrombotic risk. Mutated is present in 9%-15% of chronic lymphocytic leukaemia cases and on its own correlates with improved responsiveness to ibrutinib, but is associated with additional adverse genetic abnormalities including and mutations, which traditionally confer adverse outcomes.

Comparison of therapy-related myelodysplastic syndrome with ring sideroblasts and de novo myelodysplastic syndrome with ring sideroblasts.

Presence of RS is closely associated with SF3B1 mutation in de novo MDS. RS is also present in a subset of therapy-related MDS (t-MDS), but data is not available in t-MDS with RS (t-MDS-RS). Using NGS...

Ring sideroblasts in AML are associated with adverse risk characteristics and have a distinct gene expression pattern.

Ring sideroblasts (RS) emerge as result of aberrant erythroid differentiation leading to excessive mitochondrial iron accumulation, a characteristic feature for myelodysplastic syndromes (MDS) with mu...

Associations of Pathogenic Variants in MLH1, MSH2, and MSH6 With Risk of Colorectal Adenomas and Tumors and With Somatic Mutations in Patients With Lynch Syndrome.

Lynch syndrome is caused by variants in DNA mismatch repair (MMR) genes and associated with an increased risk of colorectal cancer (CRC). In patients with Lynch syndrome, CRCs can develop via differen...

Low-Grade Myelodysplastic Syndromes With Preserved CD34+ B-Cell Precursors (CD34+ Hematogones).

B-cell progenitors (hematogones) are markedly decreased or completely absent in the bone marrows of myelodysplastic syndromes (MDS), and the finding is considered as an important feature in MDS flow c...

Quantitative and qualitative impairments in GATA2 and myeloid neoplasms.

GATA2 is a key transcription factor critical for hematopoietic cell development. During the past decade, it became clear that heterozygous germline mutations in the GATA2 gene cause bone marrow failur...

This study is being done to see how safe an investigational drug is and test how well it will work to help people with refractory/relapsed myelodysplastic syndrome (MDS) or chronic myelomo...

Determination of the Feasibility of Tumoural Somatic Mutations Detection in Blood of Patients With Ovarian Cancer

BOVARY-Pilot is a monocentric prospective transversal pilot study with a total duration of 6 months. The purpose of this study is to determine the feasibility of detecting somatic tumor mu...

Erlotinib Study for Myelodysplastic Syndrome (MDS)

The purpose of this research study is to find out what effects, good and/or bad, erlotinib has on the patient and their myelodysplastic syndrome. Erlotinib has been approved by the Food an...

Identification of Molecular Defects in Idiopathic Cytopenia of Undetermined Significance

Medical and Biotech [MESH] Definitions

A myelodysplastic/myeloproliferative disorder characterized by myelodysplasia associated with bone marrow and peripheral blood patterns similar to CHRONIC MYELOID LEUKEMIA, but cytogenetically lacking a PHILADELPHIA CHROMOSOME or bcr/abl fusion gene (GENES, ABL).

A syndrome characterized by CHRONIC KIDNEY FAILURE and GONADAL DYSGENESIS in phenotypic females with karyotype of 46,XY or 46,XX. It is caused by donor splice-site mutations of Wilms tumor suppressor gene (GENES, WILMS TUMOR) on chromosome 11.

Clonal myeloid disorders that possess both dysplastic and proliferative features but are not properly classified as either MYELODYSPLASTIC SYNDROMES or MYELOPROLIFERATIVE DISORDERS.

A myelodysplastic-myeloproliferative disease characterized by monocytosis, increased monocytes in the bone marrow, variable degrees of dysplasia, but an absence of immature granulocytes in the blood.

An autosomal dominant disorder with an acronym of its seven features (LENTIGO; ELECTROCARDIOGRAM abnormalities; ocular HYPERTELORISM; PULMONARY STENOSIS; abnormal genitalia; retardation of growth; and DEAFNESS or SENSORINEURAL HEARING LOSS). This syndrome is caused by mutations of PTPN11 gene encoding the non-receptor PROTEIN TYROSINE PHOSPHATASE, type 11, and is an allelic to NOONAN SYNDROME. Features of LEOPARD syndrome overlap with those of NEUROFIBROMATOSIS 1 which is caused by mutations in the NEUROFIBROMATOSIS 1 GENES.
