    en.wikipedia.org/wiki/Hereditary_elliptocytosis

    Hematology. Hereditary elliptocytosis, also known as ovalocytosis, is an inherited blood disorder in which an abnormally large number of the person's red blood cells are elliptical rather than the typical biconcave disc shape. Such morphologically distinctive erythrocytes are sometimes referred to as elliptocytes or ovalocytes.

    en.wikipedia.org/wiki/List_of_genetic_disorders

    The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.

    101,100 (2015) [9] Multiple myeloma (MM), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibodies. [6] Often, no symptoms are noticed initially. [10] As it progresses, bone pain, anemia, renal insufficiency, and infections may occur. [10]

  5. Polyploidy - Wikipedia

    en.wikipedia.org/wiki/Polyploidy

    Polyploidy is the result of whole-genome duplication during the evolution of species. It may occur due to abnormal cell division, either during mitosis, or more commonly from the failure of chromosomes to separate during meiosis or from the fertilization of an egg by more than one sperm. [1]

    en.wikipedia.org/wiki/Turner_syndrome

    Turner syndrome (TS), also known as 45,X, or 45,X0, is a genetic disorder in which cells have only one X chromosome or are partially missing an X chromosome (sex chromosome monosomy) leading to the complete or partial deletion of the pseudoautosomal regions (PAR1, PAR2) in the affected X chromosome. [2][6][7] Most people have two sex ...

    en.wikipedia.org/wiki/Chromosome_abnormality

    Chromosome abnormality. A chromosomal abnormality, chromosomal anomaly, chromosomal aberration, chromosomal mutation, or chromosomal disorder is a missing, extra, or irregular portion of chromosomal DNA. [1][2] These can occur in the form of numerical abnormalities, where there is an atypical number of chromosomes, or as structural ...

  8. Patau syndrome - Wikipedia

    en.wikipedia.org/wiki/Patau_syndrome

    Patau syndrome. Patau syndrome is a syndrome caused by a chromosomal abnormality, in which some or all of the cells of the body contain extra genetic material from chromosome 13. The extra genetic material disrupts normal development, causing multiple and complex organ defects. This can occur either because each cell contains a full extra copy ...

    en.wikipedia.org/wiki/Chronic_granulomatous_disease

    Chronic granulomatous disease (CGD), also known as Bridges–Good syndrome, chronic granulomatous disorder, and Quie syndrome, [1] is a diverse group of hereditary diseases in which certain cells of the immune system have difficulty forming the reactive oxygen compounds (most importantly the superoxide radical due to defective phagocyte NADPH oxidase) used to kill certain ingested pathogens.
