In Distal Trisomy 10q disorder, end or distal portion of the q (long) arm of the chromosome number 10 appears to be present three times, rather than two times as it is supposed to be. This extra arm results in chromosome 10 trisomy, meaning that three arms are present. Depending on the length of the aberrant arm, the severity can vary from case ...
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 ...
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.

Complete trisomy 8 causes severe abnormalities on the developing fetus and can be a cause of miscarriage. [2] [3] Complete trisomy 8 is usually a gestational lethal condition, whereas trisomy 8 mosaicism is less severe and individuals with a low proportion of affected cells may exhibit a comparatively mild range of physical abnormalities and developmental delay.

Angelman syndrome ( AS) is a genetic disorder that mainly affects the nervous system. [ 6] Symptoms include a small head and a specific facial appearance, severe intellectual disability, developmental disability, limited to no functional speech, balance and movement problems, seizures, and sleep problems.

A small supernumerary marker chromosome ( sSMC) is an abnormal extra chromosome. It contains copies of parts of one or more normal chromosomes and like normal chromosomes is located in the cell's nucleus, is replicated and distributed into each daughter cell during cell division, and typically has genes which may be expressed.
