What is MYD88 testing?

The MYD88 L265P mutation has been identified in the majority of patients with Waldenström macroglobulinemia and lymphoplasmacytic lymphoma (LPL) and is useful in differentiating LPL from other low-grade B-cell lymphoproliferative disorders that may be considered in the differential diagnosis.

What is MYD88 mutation?

MYD88 mutation is the most common genetic abnormality in the activated B-cell-like (ABC) subtype of diffuse large B-cell lymphoma (DLBCL), detected in 40% of cases. Mutations are rare in the germinal center B-cell-like (GCB) subtype, so mutation analysis can be useful to differentiate between the ABC and GCB subtypes.

What is Waldenstrom syndrome?

Waldenstrom macroglobulinemia (mak-roe-glob-u-lih-NEE-me-uh) is a rare type of cancer that begins in the white blood cells. If you have Waldenstrom macroglobulinemia, your bone marrow produces too many abnormal white blood cells that crowd out healthy blood cells.

What chromosome is MYD88 on?

What is the MYD88 pathway?

MyD88 is the canonical adaptor for inflammatory signaling pathways downstream of members of the Toll-like receptor (TLR) and interleukin-1 (IL-1) receptor families. MyD88 links IL-1 receptor (IL-1R) or TLR family members to IL-1R-associated kinase (IRAK) family kinases via homotypic protein-protein interaction.

Where is MyD88 found?

Myeloid differentiation primary response 88 (MYD88) is a protein that, in humans, is encoded by the MYD88 gene….

Is MyD88 a TLR?

MyD88, a downstream adaptor protein of TLR, is critical in the signal transduction of the TLR signaling pathway. The TLR signaling is mainly divided into MyD88-dependent and MyD88-independent pathways. With the exception of TLR3, all TLRs mediate the downstream signaling pathway via MyD88 (Falck-Hansen et al., 2013).

Is Waldenstrom leukemia?

Waldenstrom macroglobulinemia (WM) is a type of non-Hodgkin lymphoma (NHL). The cancer cells make large amounts of an abnormal protein (called a macroglobulin). Another name for WM is lymphoplasmacytic lymphoma.

Is Waldenstrom inherited?

Waldenström macroglobulinemia is not inherited, and most affected people have no history of the disorder in their family. The condition usually arises from genetic changes in blood cells that are acquired during a person’s lifetime (somatic variants), which are not inherited.

Is lymphoplasmacytic lymphoma curable?

Waldenström macroglobulinemia (WM), also called “lymphoplasmacytic lymphoma,” is a rare, indolent (slow-growing) blood cancer that is treatable with available therapies but is not curable.
