What it is Filled

A genetic disorder caused by an abnormality in the number or structure of chromosomes rather than a single gene, including aneuploidies such as Down, Edwards, Patau, Turner and Klinefelter syndromes, deletion syndromes such as 16p11.2, 6pter-p24 and Xp21 deletions, duplication syndromes, translocations, ring chromosomes and small supernumerary marker chromosomes, detected by karyotyping, microarray and sequencing and often arising as new events at conception; effects range from mild to severe and management is multidisciplinary.

Why it exists Filled

Let an agent explain chromosomal diseases and their kinds in neutral clinical terms, relay causes, testing and management from genetics sources, describe support and counselling, and route families and individuals to clinical geneticists and genetic counsellors.

Distinguishing features Filled

  • Chromosome-level change
  • Number or structure
  • Often de novo
  • Variable effects

What robots and AI may and may not do Filled

Must not

  • Interpret a person's genetic test result or variant of uncertain significance.
  • Use stigmatizing or outdated language for people with chromosomal conditions.
  • Advise on pregnancy decisions in a particular case.
  • Disclose a person's genetic information without consent.

Only with a human decision

  • Any decision on genetic testing, diagnosis or pregnancy.

May

  • Explain kinds of chromosomal disease and how they differ from single-gene disorders.
  • Point families to genetic counselling services.

Moral aspects Filled

  • People with chromosomal conditions deserve dignity and full lives, not definition by a diagnosis.
  • Genetic information affects whole families and can lead to discrimination.

Who is affected

  • People with chromosomal conditions
  • Families
  • Prospective parents

Owners Filled

Steward

The treating clinician and genetic counsellor for each family.

Master systems

  • Clinical variant databases

  • Not a visible object as a category; features vary by condition.

Capabilities and actions required Filled

Sources Filled

  1. Wikidata item Q4501577: chromosomal disease - identity and sense of the item
  2. Wikipedia: Chromosomal disease - general description of the item

Open questions

  • Should aneuploidy and deletion syndrome be separate primary entries?
  • How should genetics sources be linked?
  • The registry entry has merged aliases naming specific syndromes; should they be split off?
