    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.

  3. Chromosome abnormality - Wikipedia

    en.wikipedia.org/wiki/Chromosome_abnormality

    The three major single-chromosome mutations: deletion (1), duplication (2) and inversion (3). The two major two-chromosome mutations: insertion (1) and translocation (2). When the chromosome's structure is altered, this can take several forms: [16] Deletions: A portion of the chromosome is missing or has been deleted.

    Chromosomal deletion syndrome; Chromosome 5q deletion syndrome; Chronic fatigue syndrome; Chronic functional abdominal pain; Chronic infantile neurologic cutaneous and articular syndrome; Chronic Lyme disease; Chronic prostatitis/chronic pelvic pain syndrome; Churg–Strauss syndrome; Chédiak–Higashi syndrome; Claude's syndrome; Clinically ...

  5. Chromosomal deletion syndrome - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_deletion_syndrome

    Chromosomal deletion syndromes result from deletion of parts of chromosomes. Depending on the location, size, and whom the deletion is inherited from, there are a few known different variations of chromosome deletions. Chromosomal deletion syndromes typically involve larger deletions that are visible using karyotyping techniques.

  6. Deletion (genetics) - Wikipedia

    en.wikipedia.org/wiki/Deletion_(genetics)

    The smallest single base deletion mutations occur by a single base flipping in the template DNA, followed by template DNA strand slippage, within the DNA polymerase active site. [ 3 ] [ 4 ] [ 5 ] Deletions can be caused by errors in chromosomal crossover during meiosis , which causes several serious genetic diseases .

  7. Contiguous gene syndrome - Wikipedia

    en.wikipedia.org/wiki/Contiguous_gene_syndrome

    A contiguous gene syndrome (CGS), also known as a contiguous gene deletion syndrome, is a clinical phenotype caused by a chromosomal abnormality, such as a deletion or duplication that removes several genes lying in close proximity to one another on the chromosome. The combined phenotype of the patient is a combination of what is seen when any ...

    en.wikipedia.org/wiki/Koolen–de_Vries_syndrome

    Koolen–De Vries syndrome (KdVS), also known as 17q21.31 microdeletion syndrome, is a rare genetic disorder caused by a deletion of a segment of chromosome 17 which contains six genes. This deletion syndrome was discovered independently in 2006 by three different research groups.

  9. 13q deletion syndrome - Wikipedia

    en.wikipedia.org/wiki/13q_deletion_syndrome

    13q deletion syndrome is a rare genetic disease caused by the deletion of some or all of the large arm of human chromosome 13. Depending upon the size and location of the deletion on chromosome 13, the physical and mental manifestations will vary. It has the potential to cause intellectual disability and congenital malformations that affect a ...
