Trisomy 13 Trisomy 13, or Patau�s syndrome is the least common of the live-born trisomy disorders, with an incidence of 1 in 5000 to 1 in 2,000 live births, with affected males equal to affected females. 75% of trisomy 13 cases are due to maternal NDJ, 20% are due to a translocation, and 5% are due to mosaicism. The major midline dysmorphic features of trisomy 13 are due to a defect in the fusion of the midline prechordial mesoderm in the first three weeks of gestation. Trisomy 13 tends to present with more severe craniofacial and midline defects than are found in Trisomy 18 or 21. Trisomy 13 has the following clinical features: # Holoporsencephaly # Polydactly # Seizures # Deafness # Microcephaly # Midline Cleft lip # Midline Cleft palate # Abnormal ears # Sloping forehead # Omphalocele # Cardiac and renal anomalies # Mental retardation.
Trisomy 13 is also confirmed by karyotype with FISH analysis. 44% of these patients die within 1 month, and > 70% die within one year. Severe mental retardation exists in all survivors as per (http://pedclerk.bsd.uchicago.edu/chromosomalabnormalities.html)

What is another name for trisomy-21, commonly known as Down syndrome?
Another name for trisomy-21, commonly known as Down syndrome, is trisomy 21.
Trisomy is a mutation that results in a cell having an extra?
A trisomy is a condition in which a person has three copies of a chromosome instead of the usual two copies. A person can have full trisomy (three copies in every cell) or mosaic trisomy (three copies in some cells but not all).
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.
What are alternative names for Patau syndrome?
Patau's Syndrome Trisomy 13 Syndrome Trisomy D Syndrome Trisomie 13 Trisomee Trisome Trisomic Chromosomal Abnormalities, Chromosome Anomalies, Disorder Fetal Aneuploidy
Why is a karyotype called a trisomy?
A karyotype refers to the number and appearance of chromosomes in an individual's cells. Trisomy specifically refers to the presence of an extra copy of a chromosome, resulting in a total of three copies instead of the usual two. Therefore, a karyotype with a trisomy indicates the presence of this chromosomal abnormality.

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.
What is another name for trisomy-21, commonly known as Down syndrome?
Another name for trisomy-21, commonly known as Down syndrome, is trisomy 21.
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.
Trisomy is a mutation that results in a cell having an extra?
A trisomy is a condition in which a person has three copies of a chromosome instead of the usual two copies. A person can have full trisomy (three copies in every cell) or mosaic trisomy (three copies in some cells but not all).
Are there cases of trisomy besides down syndrome that can survive?
My son is 3 years old with full trisomy 18. I have some videos on youtube that I've put together with lots of trisomy families I've found on facebook. My awareness video is of over 100 surviving kids of trisomy 13 and 18. Just go to youtube and search 'trisomy awareness' or trisomy advocacy' and you'll find them. There is also a website called 'livingwithtrisomy13.com' that has stories of over 100 trisomy 13 kids on it. I, also, personally know of two kids with trisomy 8. So, yes, there are cases of kids surviving trisomies other than trisomy 21 (Down Syndrome). :) Alisha Hauber
