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.

∙ 12y agoTrisomy means that there are 3 copies of a chromosome (instead of the usual 2).
The number that follows 'trisomy' is the chromosome which there are 3 copies of. Therefore trisomy 13 means there are 3 copies of chromosome 13.
(Trisomy 21 would be 3 copies of chromosome 21, etc.)

What is an example of a disorder associated with an error in the number of chromosomes present?
Down syndrome (trisomy 21) is a disorder associated with an error in the number of chromosomes present. Other examples of disorders associated with an error in the number of chromosomes are Trisomy 18 (Edwards Syndrome), Trisomy 13 (Patau Syndrome), Triple X syndrome, and Klinefelter Syndrome.
Trisomy-21 results from a mutation to the chromosomes in?
Gametes
What are the major chromosomal changes in trisomy?
Trisomy is defined as the presence of three homologous chromosomes. For example, Down's Syndrome is caused by trisomy-21, 3 copies of chromosome 21.
When Having three copies of chromosomes 21 leads to a disorder known as trisomy 21 or more commonly as?
Down syndrome is trisomy 21
What is the presence of three of a particular chromosome?
This is known as a trisomy. So if there are 3 of chromosome number 13, you would call it trisomy 13.
What is an example of a disorder associated with an error in the number of chromosomes present?
Down syndrome (trisomy 21) is a disorder associated with an error in the number of chromosomes present. Other examples of disorders associated with an error in the number of chromosomes are Trisomy 18 (Edwards Syndrome), Trisomy 13 (Patau Syndrome), Triple X syndrome, and Klinefelter Syndrome.
What is the cause of holoprosencephaly?
Holoprosencephaly has no single cause, but about half of all cases are associated with abnormal karyotype (abnormal numbers of chromosomes), especially trisomy 13 (extra copy of chromosome 13) and trisomy 15 (extra copy of chromosome 15).
What part of the body is involved in Trisomy 21?
The root of Trisomy 21 is within the chromosomes of the body cells.
Trisomy-21 results from a mutation to the chromosomes in?
Gametes
Is klinefelter's syndrome monosomy or trisomy?
A trisomy. A monosomy is when there is only one of a chromosome. A trisomy is when there are three of a chromosome. In Klinefelter's syndrome, there are three sex chromosomes.
Meiosis is important because it allows a mixing of the gene pool or?
Meiosis insures the correct number of chromosomes. Without all 46 chromosomes, illnesses such as trisomy 13 and huntington's disease occur.
Can a male with 48 chromosomes survive?
A human male normally has 46 chromosomes. Some configurations of 48 chromosomes would result in a viable male offspring. This individual would have a trisomy of the sex chromosomes such as XYY and also a trisomy of chromosome 21 and have Down Syndrome.
What are the major chromosomal changes in trisomy?
Trisomy is defined as the presence of three homologous chromosomes. For example, Down's Syndrome is caused by trisomy-21, 3 copies of chromosome 21.
What is the incidence of patau syndrome?
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.
Is trisomy 13 curable?
NO
When Having three copies of chromosomes 21 leads to a disorder known as trisomy 21 or more commonly as?
Down syndrome is trisomy 21
Which of the following are example(s) of trisomy---Turner Syndrome Down's Syndrome or Klinefelter's Syndrome?
Trisomy means having three copies of a chromosomes. Turner's syndrome is NOT an example of trisomy. Someone with Turner's syndrome has only one X chromosome. Down's syndrome IS an example of trisomy. Someone with Down's syndrome has 3 copies of chromosome 21. Klinefelter's syndrome is a tricky one. On one hand, it would be considered trisomy because they have 3 sex chromosomes. However, they are not all the SAME sex chromosomes. Someone with Klinefelter's has 2 X chromosomes and one Y chromosome.
