Cytogenetically normal acute myeloid leukemia (CN-AML) Overview Cytogenetically normal acute myeloid leukemia (CN-AML) is a common subtype of AML where bone marrow cells show normal chromosomes under a microscope, despite the presence of leukemia. Because standard chromosomal tests appear normal, diagnosis relies heavily on molecular genetic testing to identify specific gene mutations that guide treatment and prognosis. Symptoms Cytogenetically normal acute myeloid leukemia (CN-AML) symptoms result from a rapid overproduction of abnormal, immature white blood cells in the bone marrow, which crowds out healthy blood cells. The most common indicators are fatigue, increased susceptibility to infections, easy bruising or bleeding, fever, and unexplained weight loss. Because healthy blood cell production is disrupted, the signs and symptoms of CN-AML manifest in three main categories: 1. Low Red Blood Cells (Anemia)Extreme tiredness and weakness Pale skin and lips Shortness of breath, even ...
Activated PI3K delta syndrome (APDS) Overview Activated PI3K-delta syndrome (APDS) is a rare primary immunodeficiency caused by genetic mutations that lead to a hyperactive PI3K\(\delta \) pathway. This immune system impairment primarily causes recurrent respiratory infections, chronic viral infections, enlarged lymph nodes, and autoimmune issues, significantly increasing the risk of lymphoma. Symptoms 1. Frequent and Severe Infections Because the immune system’s white blood cells (B cells and T cells) fail to function properly, patients are highly susceptible to: Respiratory Tract : Recurrent pneumonia, bronchitis, and chronic cough. Ear and Sinus: Frequent ear infections (otitis media) and persistent sinusitis, which can sometimes lead to hearing loss Viral Infections : Chronic or severe viral infections, particularly from the herpesvirus family (e.g., Epstein-Barr virus/EBV, cytomegalovirus/CMV, and herpes simplex). 2. Lymphoproliferation Abnormal clumping and overproduction of whit...
