Q: how is the genetic abnormality patau syndrome inherited?

Non-disjunction.: The majority of cases of the lethal patau or trisomy 13 syndrome are caused by nondisjunction (47, +13) related to advanced maternal age. Robertsonian translocations of either parent can increase the risk for that couple, although most affected embryos die in utero.

Q: whats patau syndrome?

What is it.: Patau's syndrome is the presence of various dysmorphic features in a child a set of three chromosomes 13. This is called trisomy, in this case, trisomy 13.

Q: what causes patau syndrome?

It's not: Patau syndrome arises from a non-disjunction event prevents the 18 chromosome from dividing its pair &amp; sends 2, not one to the egg. At conception the sperm brings along another 18 &amp; there ends up being 3. The presence of the extra 18 causes the developing fetus to misread the genetic instructions and many defects occur.

Question 1

how can we treat patau syndrome?

Accepted Answer

Supportively: Patau is a chromosomal abnormality of trisomy 13.  There is no treatment of the cause but the various symptoms can be treated. For example, heart defects can be repaired, polydactyly can be corrected. However, many children live only a short time so often the goal is comfort care.

Question 2

what is the testing process like for patau syndrome?

Accepted Answer

13 trisomy: Patau syndrome is caused by13 trisomy. It can be suspected by find the characteristic malformations including, cleft lip/palate/ eye and ear abnormalities, scalp defects, congenital heart disease and polydactyly. Definitive diagnosis is by chromosomal analysis revealing an extra 13 chromosome. Testing can be done from blood, skin, a cvs or amniocentesis sample or in tissue from a poc.

Question 3

what is the definition or description of: patau syndrome?

Accepted Answer

Patau syndrome: Patau syndrome is the least common and most severe of the viable autosomal trisomies. Median survival is fewer than 3 days. First was identified as a chromosomal syndrome in 1960.  Patau syndrome is caused by an extra copy of chromosome 13.

Question 4

is hemophilia linked to patau syndrome?

Accepted Answer

No, not linked.: Hemophilia a and hemophilia b are caused by mutations in genes f8 and f9, respectively, on the x chromosome. Patau syndrome results from trisomy 13 (the presence of an extra #13 chromosome).

Question 5

are there genes to tell how long someone will survive with patau syndrome?

Accepted Answer

No: Most infants with patau syndrome die within their first year. There is no genetic test to explain the variation in survival.

Question 6

how to know if certain people are more likely to get trisomy number 13 patau syndrome than others?

Accepted Answer

Amniocentesis: Trisomy 13 can be diagnosed by amniocentesis with genetic study of the chromosomes  prior to birth.

Question 7

i heard that certain people are more likely to get trisomy number 13 patau syndrome than others, why is that?

Accepted Answer

Child of older mom: Increasing maternal age increases the risk for chromosome disorders, highlighted by trisomy 21 (down syndrome) but applying to rarer trisomies like the trisomy 13 causing patau syndrome (1 in 8000 births or so).  Risks for trisomy increase gradually with maternal age, going from <1 in 2000 under 30 to ~ 1 in 50 over age 40, with age 35 arbitrarily set as high risk (~1 in 200).

Question 8

how is the genetic abnormality patau syndrome inherited?

Non-disjunction.: The majority of cases of the lethal patau or trisomy 13 syndrome are caused by nondisjunction (47, +13) related to advanced maternal age. Robertsonian translocations of either parent can increase the risk for that couple, although most affected embryos die in utero.
