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 ]
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.
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. There are over 6,000 known genetic disorders in humans.
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.
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 .
Feline disease refers to infections or illnesses that affect cats. They may cause symptoms, sickness or the death of the animal. Some diseases are symptomatic in one cat but asymptomatic in others. Feline diseases are often opportunistic and tend to be more serious in cats that already have concurrent sicknesses.
49,XXXXY syndrome is an extremely rare aneuploidic sex chromosomal abnormality. It occurs in approximately 1 out of 85,000 to 100,000 males. [1] [2] [3] This syndrome is the result of maternal non-disjunction during both meiosis I and II. [4] It was first diagnosed in 1960 and was coined Fraccaro syndrome after the researcher. [2]
