Smith–Magenis syndrome (SMS), also known as 17p-microdeletion syndrome, is a microdeletion syndrome characterized by an abnormality in the short (p) arm of chromosome 17. [1] It has features including intellectual disability, facial abnormalities, difficulty sleeping, and numerous behavioral problems such as self-harm. Smith–Magenis ...
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 ...
17q12 microdeletion syndrome, also known as 17q12 deletion syndrome, is a rare chromosomal anomaly caused by the deletion of a small amount of material from a region in the long arm of chromosome 17. It is typified by deletion of the HNF1B gene, resulting in kidney abnormalities and renal cysts and diabetes syndrome .
Koolen–De Vries syndrome (KdVS), also known as 17q21.31 microdeletion syndrome, is a rare genetic disorder caused by a deletion of a segment of chromosome 17 which contains six genes. This deletion syndrome was discovered independently in 2006 by three different research groups. [1] [2] [3] [4]
Nearby regions on chromosome 16 may also be affected. Notably, deletion of SH2B1 is associated with obesity and may be involved in the pathogenesis of obesity observed in the syndrome. [9] 16p11.2 deletion typically occurs by de novo mutation. Approximately 7% of affected individuals inherit the mutation from a parent in an autosomal dominant ...
Frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17) is an autosomal dominant neurodegenerative tauopathy and Parkinson plus syndrome. [3] FTDP-17 is caused by mutations in the MAPT (microtubule associated protein tau) gene located on the q arm of chromosome 17, and has three cardinal features: behavioral and personality changes, cognitive impairment, and motor symptoms.
Chromosome 17 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 17 spans more than 84 million base pairs (the building material of DNA ) and represents between 2.5 and 3% of the total DNA in cells .
Potocki–Lupski syndrome (PTLS), also known as dup(17)p11.2p11.2 syndrome, trisomy 17p11.2 or duplication 17p11.2 syndrome, is a contiguous gene syndrome involving the microduplication of band 11.2 on the short arm of human chromosome 17 (17p11.2). [1] The duplication was first described as a case study in 1996. [2]
