Chip mutation
Clonal hematopoiesis of indeterminate potential, or CHIP, is a common aging-related phenomenon in which hematopoietic stem cells (HSCs) or other early blood cell progenitors contribute to the formation of a genetically distinct subpopulation of blood cells. As the name suggests, this … See more The first major evidence for the existence of prevalent clonal hematopoiesis in healthy people was put forth in the 1990s. Using the HUMARA assay, scientists found that there was nonrandom X-inactivation of … See more The advent of next-generation DNA sequencing has allowed for the targeted identification of somatic mutations involved in clonal hematopoiesis at the population level. The studies undertaken as of 2024 are largely consistent in their main findings. One … See more Clonal hematopoiesis by itself is not considered to be a hematologic cancer; nevertheless, evidence is mounting that this condition may adversely affect human health. It has been … See more Clonal hematopoiesis is thought to originate with the hematopoietic stem cells that make blood. An adult human has approximately 10,000 to 20,000 HSCs. The fact that these cells are maintained for life and each HSC may acquire about one mutation in a … See more Clonal hematopoiesis is sometimes compared to the unrelated blood disorders of monoclonal gammopathy of undetermined significance (MGUS) See more • Acute myeloid leukemia • Haematopoiesis • Hematopoietic stem cell • Hematopoietic stem cell transplantation • Hematology See more WebSome of these mutations, Jaiswal explains, give certain blood stem cells a competitive advantage over others, and they begin to dominate the bone marrow niches where such stem cells live. “In people with CHIP, we see that anywhere from 4% to 100% of their HSCs are clones derived from a single mutated stem cell,” Jaiswal said.

WebThe most commonly found mutations in CHIP are in genes that chemically modify DNA or chromatin to regulate transcription (DNMT3A, TET2, ASXL1). CHIP is rare in the young, but becomes common with aging. Between 10-30% of the elderly have a clonal mutation meeting the definition of CHIP. Those with CHIP are at markedly increased risk of ... WebClonal hematopoiesis of indeterminate potential (CHIP) is defined as the presence of myeloid cancer-associated, somatic mutations with a variant allele frequency (VAF) of ≥2% in the hematopoietic cells of individuals without hematologic malignancy. 1 Its prevalence steeply increases with age, affecting about 15-20% of individuals of ≥60 years, indicating …
