  2. Chromosome 5q deletion syndrome - Wikipedia

    en.wikipedia.org/wiki/Chromosome_5q_deletion...

    Chromosome 5q deletion syndrome is an acquired, hematological disorder characterized by loss of part of the long arm (q arm, band 5q33.1) of human chromosome 5 in bone marrow myelocyte cells. This chromosome abnormality is most commonly associated with the myelodysplastic syndrome.

  3. Chromosome 15q partial deletion - Wikipedia

    en.wikipedia.org/wiki/Chromosome_15q_partial...

    Chromosome 15q partial deletion is a rare human genetic disorder, caused by a chromosomal aberration in which the long ("q") arm of one copy of chromosome 15 is deleted, or partially deleted. [1] Like other chromosomal disorders, this increases the risk of birth defects, developmental delay and learning difficulties, however, the problems that ...

  4. Chromosome 15q trisomy - Wikipedia

    en.wikipedia.org/wiki/Chromosome_15q_trisomy

    Chromosome 15q duplication is an extremely rare genetic disorder in which there is an excess copy of a segment of DNA found on the long ("q") arm of human chromosome 15.As a result, affected cells contain a total of 3 copies of the duplicated bases, instead of the usual 2 copies - one inherited from the mother and one from the father - found in a normal human diploid genome.

  5. Isochromosome - Wikipedia

    en.wikipedia.org/wiki/Isochromosome

    The chromosome consists of two copies of either the long (q) arm or the short (p) arm because isochromosome formation is equivalent to a simultaneous duplication and deletion of genetic material. Consequently, there is partial trisomy of the genes present in the isochromosome and partial monosomy of the genes in the lost arm. [2]

  6. Chromosome 5 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_5

    Changes to chromosome 5 include an extra segment of the short (p) or long (q) arm of the chromosome in each cell (partial trisomy 5p or 5q), a missing segment of the long arm of the chromosome in each cell (partial monosomy 5q), and a circular structure called ring chromosome 5. A ring chromosome occurs when both ends of a broken chromosome are ...

  7. Chromosome 15 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_15

    Chromosome 15 is an acrocentric chromosome, with a very small short arm (the "p" arm, for "petite"), which contains few protein coding genes among its 19 million base pairs. It has a larger long arm (the "q" arm) that is gene rich, spanning about 83 million base pairs.

  8. 15q overgrowth syndrome - Wikipedia

    en.wikipedia.org/wiki/15q_overgrowth_syndrome

    Facial dysmorphism (long thin face, prominent forehead, down-slanting palpebral fissures, prominent nose with broad nasal bridge, and prominent chin) Overgrowth (pre- and post-natal) Renal anomalies (horseshoe kidney, renal agenesis, and hydronephrosis) Mild to severe learning difficulties; Behavioural anomalies

  9. Isodicentric 15 - Wikipedia

    en.wikipedia.org/wiki/Isodicentric_15

    Isodicentric 15, also called marker chromosome 15 syndrome, [2] idic(15), partial tetrasomy 15q, or inverted duplication 15 (inv dup 15), is a chromosome abnormality in which a child is born with extra genetic material from chromosome 15. People with idic(15) are typically born with 47 chromosomes in their body cells, instead of the normal 46.
