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 ...
Fragile X syndrome. Fragile X syndrome ( FXS) is a genetic disorder characterized by mild-to-moderate intellectual disability. [ 1] The average IQ in males with FXS is under 55, while about two thirds of affected females are intellectually disabled. [ 3][ 4] Physical features may include a long and narrow face, large ears, flexible fingers, and ...
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 ...
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. This can occur either because each cell contains a full extra copy ...
Chromosomal Mutation. 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] It was first described by Jérôme Lejeune in 1963. [ 3]
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 ...
Robertsonian translocation ( ROB) is a chromosomal abnormality where the entire long arms of two different chromosomes become fused to each other. It is the most common form of chromosomal translocation in humans, affecting 1 out of every 1,000 babies born. [ 1] It does not usually cause medical problems, though some people may produce gametes ...
