Chromosome 13
This is known as a trisomy. So if there are 3 of chromosome number 13, you would call it trisomy 13.
Patau syndrome is the result of trisomy 13. Trisomy 13 is usually caused by having an extra chromosome in every cell in the body. Every cell in the human body should contain two chromosomes, one from each parent, however every one in sixteen thousand newborn has three chromosomes. The result of a third chromosome can mean physical disabilities. Most children die within a few days after birth. The disease is not inherited.
They don't know yet, Recent research suggests that a small number of Tourette syndrome cases may be caused by a defect on chromosome 13 of gene SLITRK1. and some other chromosomes like 7. There now busy with a study to find the genes that may cause tourette syndrome, results will be given by 2018
There is no 'deletion chromosome'. You mean chromosome deletion, and it is a phenomenon where a chromosome disappears from cell's genetic layout.
Chromosome 13
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18

Wilson's Disease is a disease in which the body contains too much copper. This is due to chromosome 13 malfunctions. Chromosome 13 is the chromosome held with the repsonsibilty of cleansing the liver. If it does not work, the liver and brain will store copper causing many problems within the body.
Trisomy 18 is a form of chromosomal aberration. It is neither recessive nor dominant. Neither does it show co-dominance or incomplete dominance factor. It arises due to the presence of an extra chromosome 18 in the somatic cells.
Patau syndrome, also known as Trisomy 13, is an abnormality of chromosomes in which a patient has an additional 13th chromosome due to a failure of chromosomes to split during meiosis. It can cause the following conditions: motor & mental retardation, extra digits, microcephaly, low-set ears, failure of the forbrain to divide properly, heart defects, eye defects, cleft palate, spinal defects, abnormal genitalia, abnormal palm patterns or overlapping of fingers over thumb. Photos of children with Patau Syndrome - Trisomy 13.
due to deletion of seven genes (or some subset thereof) on chromosome 15 (q 11-13) are deleted or unexpressed (chromosome 15q partial deletion) on the paternal chromosome.
