Distal trisomy 10 is a rare chromosomal disorder that causes several physical defects and intellectual disability. [5] Humans, like all sexually reproducing species, have somatic cells that are in diploid [ 2N] state, meaning that N represent the number of chromosomes, and 2 the number of their copies. In humans, there are 23 chromosomes, but ...
The Pallister–Killian syndrome (PKS), also termed tetrasomy 12p mosaicism or the Pallister mosaic aneuploidy syndrome, is an extremely rare and severe genetic disorder. PKS is due to the presence of an extra and abnormal chromosome termed a small supernumerary marker chromosome (sSMC). sSMCs contain copies of genetic material from parts of ...
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 more ...

The Dp(16)1Yu model (also referred to as Dp(16)1Yey) contains a partial duplication of the mouse chromosome 16 (MMU16). Unlike the Ts65Dn model, Dp(16)1Yu contains a duplication of only the parts of chromosome 16 that are homologous to human chromosome 21. This makes the Dp(16)1Yu model a more genetically accurate representation of Down Syndrome.

Marker chromosome. A marker chromosome (mar) is a small fragment of a chromosome which generally cannot be identified without specialized genomic analysis due to the size of the fragment. [1] The significance of a marker is variable as it depends on what material is contained within the marker. [2] The large majority of these marker chromosomes ...
