    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. 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 .

    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. [1] [2] [3] [4]

    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.

  6. 17q12 microdeletion syndrome - Wikipedia

    en.wikipedia.org/wiki/17q12_microdeletion_syndrome

    17q12 microdeletion syndrome is an autosomal dominant disorder, where one copy of the relevant mutation is enough to cause the condition. Most cases are de novo, or spontaneous mutations that do not occur in the proband's parents; [10] approximately 75% are de novo, while 25% are inherited. [4]

    An example of this type of system is the 22q Deletion Clinic at SickKids Hospital in Toronto, Canada, which provides children with 22q11 deletion syndrome ongoing support, medical care and information from a team of health care workers. [54] Metirosine (methyltyrosine) is used as an off-label treatment for DiGeorge syndrome. [55]

    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 ...
