You asked: Which of the following is associated with Down syndrome?

Having Down syndrome also increases the risk of developing Alzheimer’s disease. Other problems. Down syndrome may also be associated with other health conditions, including endocrine problems, dental problems, seizures, ear infections, and hearing and vision problems.

What is Down syndrome associated with?

Down syndrome is a chromosomal condition that is associated with intellectual disability, a characteristic facial appearance, and weak muscle tone (hypotonia) in infancy. All affected individuals experience cognitive delays, but the intellectual disability is usually mild to moderate.

Which of the following is a symptom of Down syndrome?

Short neck, with excess skin at the back of the neck. Flattened facial profile and nose. Small head, ears, and mouth. Upward slanting eyes, often with a skin fold that comes out from the upper eyelid and covers the inner corner of the eye.

Is all associated with Down syndrome?

Acute lymphoblastic leukemia (ALL) associated with Down syndrome (ALL-DS), is predominantly a B lymphoblastic leukemia, with only very rare cases of mature B cell ALL ( Burkitt leukemia) and T-cell ALL. Trisomy 21 has an incidence of approximately 1 in 700 live births.

Which anomaly is associated with Down syndrome?

Fourteen (2%) of the cases with DS had an obstructive anomaly of the renal pelvis, including hydronephrosis. The other most common anomalies associated with cases with DS were syndactyly, club foot, polydactyly, limb reduction, cataract, hydrocephaly, cleft palate, hypospadias and diaphragmatic hernia.

What is the karyotype of Down syndrome?

The trisomy 21 karyotype figure shows the chromosomal arrangement, with the prominent extra chromosome 21. Trisomy 21 is the cause of approximately 95% of observed Down syndrome, with 88% coming from nondisjunction in the maternal gamete and 8% coming from nondisjunction in the paternal gamete.

Is Down syndrome a spectrum?

Similar to other populations (with or without a medical diagnosis), individuals with Down syndrome present a wide spectrum of physical, cognitive, and social characteristics and abilities.

What are the symptoms of Down syndrome in pregnancy?

Signs and Symptoms of Down Syndrome

  • Flat face with an upward slant to the eyes.
  • Short neck.
  • Abnormally shaped or small ears.
  • Protruding tongue.
  • Small head.
  • Deep crease in the palm of the hand with relatively short fingers.
  • White spots in the iris of the eye.
  • Poor muscle tone, loose ligaments, excessive flexibility.

How is Down syndrome detected?

Diagnostic tests that can identify Down syndrome include: Chorionic villus sampling (CVS). In CVS, cells are taken from the placenta and used to analyze the fetal chromosomes. This test is typically performed in the first trimester, between 10 and 13 weeks of pregnancy.

What are the behaviors of Down syndrome?

A young child with Down syndrome that presents with persistent oppositional, impulsive, disruptive, irritable, and aggressive behaviors should be considered under a possible mood disorder.

What are the types of Down syndrome?

There are three types of Down syndrome:

  • Trisomy 21. This is by far the most common type, where every cell in the body has three copies of chromosome 21 instead of two.
  • Translocation Down syndrome. In this type, each cell has part of an extra chromosome 21, or an entirely extra one. …
  • Mosaic Down syndrome.

Which anomaly is associated with Down syndrome quizlet?

Down syndrome results when abnormal cell division involving chromosome 21 occurs. These cell division abnormalities result in an extra partial or full chromosome 21. This extra genetic material is responsible for the characteristic features and developmental problems of Down syndrome.

Is Down syndrome a congenital anomaly?

The most common, severe congenital anomalies are heart defects, neural tube defects and Down syndrome. Although congenital anomalies may be the result of one or more genetic, infectious, nutritional or environmental factors, it is often difficult to identify the exact causes.
