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 ...
This 13-year-old rescue is as lively as a puppy with her custom-fit legs! Hear her unbelievable story of hope in this video shared on August 18: Amira (@ amira.amiracle) might have a harrowing ...
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 ...
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 large testicles. [ 1]
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 ...

1q21.1 duplication syndrome arises from microduplications of the BP3-BP4 region, containing at least seven genes and a minimum duplicated region of ~1.2 Mb of unique DNA sequence. [ 7] 1q21.1 duplication syndrome has an autosomal dominant inheritance pattern, where 18–50% of deletions happen de novo and 50–82% are inherited from their parents.
Isochromosome. Isochromosome in which the arms are mirror copies of each other. An isochromosome is an unbalanced structural abnormality in which the arms of the chromosome are mirror images of each other. [ 1] The chromosome consists of two copies of either the long (q) arm or the short (p) arm because isochromosome formation is equivalent to ...
