  2. Haemochromatosis type 3 - Wikipedia

    en.wikipedia.org/wiki/Haemochromatosis_type_3

    Haemochromatosis type 3 is a type of iron overload disorder associated with deficiencies in transferrin receptor 2. It exhibits an autosomal recessive inheritance pattern. [ 2 ] [ 3 ] [ 4 ] The first confirmed case was diagnosed in 1865 by French doctor Trousseau.

    Their repeated nature allows a unique form of mutation: the number of copies can increase or decrease when strand slippage occurs during DNA replication. (Regular point mutation still happens and could be more frequent than slippage.) [ 7 ] Their copy number not only have use in forensics and ancestry testing, [ 8 ] but are also linked to diseases.

  4. Molecular beacon - Wikipedia

    en.wikipedia.org/wiki/Molecular_beacon

    The structure of a typical molecular beacon probe. A typical molecular beacon probe is 25 nucleotides long. [citation needed] The middle 15 nucleotides are complementary to the target DNA or RNA and do not base pair with one another, while the five nucleotides at each terminus are complementary to each other rather than to the target DNA.

  5. Hereditary haemochromatosis - Wikipedia

    en.wikipedia.org/wiki/Hereditary_haemochromatosis

    Haemochromatosis is protean in its manifestations, i.e., often presenting with signs or symptoms suggestive of other diagnoses that affect specific organ systems.Many of the signs and symptoms below are uncommon, and most patients with the hereditary form of haemochromatosis do not show any overt signs of disease nor do they have premature morbidity, if they are diagnosed early, but, more ...

  6. Hemochromatosis type 4 - Wikipedia

    en.wikipedia.org/wiki/Hemochromatosis_type_4

    Type 4 hemochromatosis is caused by mutations of the SLC40A1 gene, located on the long arm of chromosome 2, specifically at 2q32.2. The SLC40A1 gene encodes ferroportin, a protein responsible for exporting iron from cells in the intestine, liver, spleen, and kidney, as well as from reticuloendothelial macrophages and the placenta.

  7. DNA Specimen Provenance Assignment - Wikipedia

    en.wikipedia.org/wiki/DNA_Specimen_Provenance...

    DNA Specimen Provenance Assay (Assignment) (DSPA) testing can be performed on specimens from a range of medical specialty areas, such as gastroenterology, obstetrics, pulmonology, radiology, urology, etc. Molecular methods are currently available to extract DNA from a variety of sources, including fresh tissue, formalin-fixed, paraffin-embedded ...

  8. Iron overload - Wikipedia

    en.wikipedia.org/wiki/Iron_overload

    Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress , as elevated intracellular iron levels increase free radical formation via the Fenton reaction .

  9. Combined bisulfite restriction analysis - Wikipedia

    en.wikipedia.org/wiki/Combined_Bisulfite...

    The first few steps of COBRA, and the molecular changes caused by each step to methylated and unmethylated CpG sites. Combined Bisulfite Restriction Analysis (or COBRA) is a molecular biology technique that allows for the sensitive quantification of DNA methylation levels at a specific genomic locus on a DNA sequence in a small sample of genomic DNA.
