    en.wikipedia.org/wiki/Cri_du_chat_syndrome

    Chromosomal Deletion Cri du chat syndrome is a rare genetic disorder due to a partial chromosome deletion on chromosome 5 . [ 1 ] Its name is a French term ("cat-cry" or " call of the cat ") referring to the characteristic cat-like cry of affected children (sound sample [1] ). [ 2 ]

  3. Cat genetics - Wikipedia

    en.wikipedia.org/wiki/Cat_genetics

    Cat genetics describes the study of inheritance as it occurs in domestic cats. In feline husbandry it can predict established traits ( phenotypes ) of the offspring of particular crosses. In medical genetics , cat models are occasionally used to discover the function of homologous human disease genes.

  4. Chromosome abnormality - Wikipedia

    en.wikipedia.org/wiki/Chromosome_abnormality

    A chromosomal abnormality, chromosomal anomaly, chromosomal aberration, chromosomal mutation, or chromosomal disorder is a missing, extra, or irregular portion of chromosomal DNA. [ 1 ] [ 2 ] These can occur in the form of numerical abnormalities, where there is an atypical number of chromosomes, or as structural abnormalities, where one or ...

    The disorder leaves the cat with a full-size body, but disproportionately short and thick legs. Dwarf cats often suffer from spinal disorders, such as lordosis (excessive curvature of the spine) and pectus excavatum (hollowed chest). [7] As with human dwarfism, there are still a lot of unknown mysteries in the science behind feline dwarfism.

  6. Chromosomal deletion syndrome - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_deletion_syndrome

    Prader–Willi (PWS) and Angelman syndrome (AS) are distinct neurogenetic disorders caused by chromosomal deletions, uniparental disomy or loss of the imprinted gene expression in the 15q11-q13 region. Whether an individual exhibits PWS or AS depends on if there is a lack of the paternally expressed gene to contribute to the region.

    Trisomy 21 – Down syndrome, an example of a polysomy at chromosome 21. Polysomy is a condition found in many species, including fungi, plants, insects, and mammals, in which an organism has at least one more chromosome than normal, i.e., there may be three or more copies of the chromosome rather than the expected two copies. [1]

  8. Patau syndrome - Wikipedia

    en.wikipedia.org/wiki/Patau_syndrome

    Patau syndrome is a syndrome caused by a chromosomal abnormality, in which some or all of the cells of the body contain extra genetic material from chromosome 13.The extra genetic material disrupts normal development, causing multiple and complex organ defects.

  9. Cat eye syndrome - Wikipedia

    en.wikipedia.org/wiki/Cat_eye_syndrome

    Cat-eye syndrome (CES) or Schmid–Fraccaro syndrome is a rare condition caused by an abnormal extra chromosome, i.e. a small supernumerary marker chromosome. [2] This chromosome consists of the entire short arm and a small section of the long arm of chromosome 22 .
