The former results in a chromosomal abnormality featured in all cells of the offspring, as in translocation carriers. Somatic translocations, on the other hand, result in abnormalities featured only in the affected cell and its progenitors, as in chronic myelogenous leukemia with the Philadelphia chromosome translocation.
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.
22q13 deletion syndrome, known as Phelan–McDermid syndrome (PMS), is a genetic disorder caused by deletions or rearrangements on the q terminal end (long arm) of chromosome 22.
Deletions are responsible for an array of genetic disorders, including some cases of male infertility, two thirds of cases of Duchenne muscular dystrophy, [1] and two thirds of cases of cystic fibrosis (those caused by ΔF508). [9] Deletion of part of the short arm of chromosome 5 results in Cri du chat syndrome. [1]
Ring chromosome 20, ring-shaped chromosome 20 or r(20) syndrome is a rare human chromosome abnormality where the two arms of chromosome 20 fuse to form a ring chromosome.The syndrome is associated with epileptic seizures, behaviour disorders and intellectual disability.
Beckwith–Wiedemann syndrome (/ ˈ b ɛ k ˌ w ɪ θ ˈ v iː d ə. m ə n /; abbreviated BWS) is an overgrowth disorder usually present at birth, characterized by an increased risk of childhood cancer and certain congenital features.
Jeffrey Lionel Dahmer (/ ˈ d ɑː m ər /; May 21, 1960 – November 28, 1994), also known as the Milwaukee Cannibal or the Milwaukee Monster, [4] was an American serial killer and sex offender who killed and dismembered seventeen males between 1978 and 1991. [5]
XXXY syndrome is a genetic condition characterized by a sex chromosome aneuploidy, where individuals have two extra X chromosomes. [2] People in most cases have two sex chromosomes: an X and a Y or two X chromosomes.
