What age does down syndrome appear? It is determined by many factors, but research suggests that there is a higher chance if the mother is older than 35 years of age. Before the age of 30, Down syndrome occurs in fewer than 1 in 1,000 pregnancies. After the age of 40, this figure rises to about 12 in 1,000.
How soon can you tell if your baby has Down syndrome? 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.
Can Down syndrome be detected later in life? Down syndrome can also be diagnosed after a baby is born. Clinicians can usually tell if a baby should be tested for Down syndrome based on a physical examination. The first test, a rapid blood test (FISH), confirms the presence of extra material from chromosome 21.
How many cases of Alice in Wonderland syndrome are there? About 166 cases of AIWS have been published in the literature, identifying various types of conditions associated with the syndrome.

Is down syndrome dominant or recessive gene?
Like cystic fibrosis, Down’s Syndrome is autosomal recessive. This means that the condition is genetic and passed down by the mother and/or the father but the condition is not shown in the parents. An autosomal recessive disorder requires two copies of the abnormal gene for the disease or trait to develop.

A Detailed Anomaly Scan done at 20 weeks can only detect 50% of Down Syndrome cases. First Trimester Screening, using bloods and Nuchal Translucency measurement, done between 10-14 weeks, can detect 94% of cases and Non-invasive Prenatal Testing (NIPT) from 9 weeks can detect 99% of Down Syndrome cases.

Today the average lifespan of a person with Down syndrome is approximately 60 years. As recently as 1983, the average lifespan of a person with Down syndrome was 25 years. The dramatic increase to 60 years is largely due to the end of the inhumane practice of institutionalizing people with Down syndrome.

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.
