	Chromosome 13 (human) - Wikipedia, the free encyclopedia
		Chromosome 13 is one of the 23 pairs of chromosomes in humans.
		Trisomy 13: Trisomy 13 occurs when each cell in the body has three copies of chromosome 13 instead of the usual two copies.
		In a small percentage of cases, trisomy 13 is caused by a rearrangement of chromosomal material between chromosome 13 and another chromosome.

		Trisomy 13 is a syndrome associated with the presence of a third (extra) number 13 chromosome.
		Trisomy 13 is associated with multiple abnormalities, including defects of the brain that lead to seizures, apnea, deafness, and eye abnormalities.
		Trisomy 13 can be diagnosed prenatally by amniocentesis with chromosome studies of the amniotic cells.

	Trisomy 18 & 13 - Lucile Packard Children's Hospital
		Again, trisomy 18 or trisomy 13 simply means there are three copies of the #18 chromosome (or of the #13 chromosome) present in each cell of the body, rather than the usual pair.
		Trisomy 18 and trisomy 13 are genetic disorders that present a combination of birth defects including severe mental retardation, as well as health problems involving nearly every organ system in the body.
		Because many babies born with trisomy 18 and trisomy 13 may not live beyond the first few days or weeks of life, it is possible that parents may have to face the fact that the baby may never go home from the hospital.

		Mosaicism for trisomy 13 is associated with a milder degree of severity, with the mildest expression typically in the lowest levels of mosaicism.
		If trisomy 13 is discovered in the prenatal period after 24 weeks of gestation or if the patient elects to continue the pregnancy diagnosed at an earlier gestational age, counseling that discusses the utility of performing a cesarean delivery for fetal indications is appropriate.
		Population-based analyses of mortality in trisomy 13 and trisomy 18.

		Trisomy 13 (Patau syndrome) occurs in approximately 1 in 10,000 live births and mosaic trisomy 13 is thought to account for about 5% of these cases (Eubanks et al, 1998).
		Individuals with mosaic trisomy 13 may present with a range of clinic findings, from the typical features of full trisomy 13 (severe mental retardation and multiple congenital anomalies) to more mild mental retardation or even normal intellectual function, milder physical features, and longer survival.
		When trisomy 13 cells are detected at amniocentesis or fetal blood sampling, it is difficult to predict which cases will be mild and which will be severe.

	Chromosomal Abnormalities: Trisomy 18, 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.
		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 Syndrome
		In individuals with Trisomy 13 Syndrome, the range and severity of associated symptoms and findings may depend on the specific location of the duplicated (trisomic) portion of chromosome 1, as well as the percentage of cells containing the abnormality.
		For example, characteristic heart defects may include an abnormal opening in the partition dividing the upper or lower chambers of the heart (atrial or ventricular septal defects) or persistence of the fetal opening between the two major arteries (aorta, pulmonary artery) emerging from the heart (patent ductus arteriosus).
		Many infants with Trisomy 13 Syndrome fail to grow and gain weight at the expected rate (failure to thrive) and have severe feeding difficulties, diminished muscle tone (hypotonia), and episodes in which there is temporary cessation of spontaneous berathing (apnea).
