About 87% of cases represent a de novo deletion, while about 13% are inherited from a parent with a chromosome translocation. [4] In the cases of familial transmission, there is a 2 to 1 excess of maternal transmission. Of the de novo cases, 80% are paternally derived. [citation needed] A more uncommon cause for WHS is the formation of a ring ...
With an incidence of 1 in 15,000 to 1 in 50,000 live births, it is suggested to be one of the most common contiguous gene deletion disorders. 5p deletions are most common de novo occurrences, which are paternal in origin in 80–90% of cases, possibly arising from chromosome breakage during gamete formation in males [citation needed]
When the chromosome's structure is altered, this can take several forms: [16] Deletions: A portion of the chromosome is missing or has been deleted. Known disorders in humans include Wolf–Hirschhorn syndrome, which is caused by partial deletion of the short arm of chromosome 4; and Jacobsen syndrome, also called the terminal 11q deletion ...
The chromosome is ~193 megabases in length. In a 2012 paper, 775 protein-encoding genes were identified on this chromosome. [4] 211 (27.9%) of these coding sequences did not have any experimental evidence at the protein level, in 2012. 271 appear to be membrane proteins. 54 have been classified as cancer-associated proteins.
16p11.2 deletion syndrome is a rare genetic condition caused by microdeletion on the short arm of chromosome 16. Most affected individuals experience global developmental delay and intellectual disability, as well as childhood-onset obesity. [1] 16p11.2 deletion is estimated to account for approximately 1% of autism spectrum disorder cases. [3] [4]
Monosomy 9p (also known as Alfi's Syndrome, 9p Minus or simply 9P-) is a rare chromosomal disorder in which some DNA is missing or has been deleted on the short arm region, "p", of one copy of chromosome 9 (9p22.2-p23). [1] [2] This deletion either happens de novo or as a result of a parent having the chromosome abnormality. [3]
ATR-16 syndrome is caused by a deletion of part of chromosome 16, from p13.3 (a band on the short end of the chromosome) to the end of the chromosome. These can either be due to a balanced translocation or a de novo deletion. [1] The genes affected include hemoglobin, alpha 1 (HBA1) and hemoglobin, alpha 2 (HBA2). [2]
Miller–Dieker syndrome, also called Miller–Dieker lissencephaly syndrome (MDLS) or chromosome 17p13.3 deletion syndrome, [1] is a micro deletion syndrome characterized by congenital malformations. Congenital malformations are physical defects detectable in an infant at birth which can involve many different parts of the body, including the ...
