Acute leukaemia in siblings

Insights

A 4-year-old boy was diagnosed with lymphoblastic leukemia, and his brother developed myeloblastic leukemia three years later. Despite the brother

Area of Science:

  • Hematology
  • Oncology
  • Genetics

Background:

  • Leukemia is a cancer of the blood or bone marrow.
  • Leukemias are broadly divided into acute and chronic, and into lymphoid or myeloid types.

Observation:

  • A 4-year-old boy was diagnosed with acute lymphoblastic leukemia (ALL).
  • Three years later, his 20-year-old brother was diagnosed with acute myeloid leukemia (AML).

Findings:

  • The younger brother achieved complete remission and remains well over six years later.
  • The older brother did not respond to treatment and died within five months.
  • No constitutional predisposition to leukemia was identified in the parents or remaining siblings.

Implications:

  • This case highlights the occurrence of distinct leukemias in closely related individuals.
  • Further research may be needed to explore potential genetic or environmental factors contributing to secondary leukemia.
  • Understanding familial leukemia patterns is crucial for early detection and personalized treatment strategies.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Disorders of Leukocytes01:27

Disorders of Leukocytes

Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
Bone Marrow Sampling and Transplants01:22

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...
