2. Causes and Risk Factors

Down Syndrome is primarily caused by the presence of an extra copy of chromosome 21, known as trisomy 21. The risk increases with maternal age, but it can occur in pregnancies of any age.

Causes and Risk Factors of Down Syndrome

CauseDetails
Genetic BasisDown Syndrome is primarily caused by the presence of an extra copy of chromosome 21, a condition known as trisomy 21.
The additional genetic material disrupts typical development and results in the characteristic features associated with Down Syndrome.
Trisomy 21The term “trisomy 21” refers to the three copies of chromosome 21 instead of the usual two.
 This extra genetic material affects physical and intellectual development.
Maternal AgeThe risk of having a child with Down Syndrome increases with maternal age.
Advanced maternal age, especially for women over 35, is associated with a higher likelihood of a pregnancy affected by Down Syndrome.
Paternal AgeWhile maternal age is a significant factor, paternal age can also play a role in the occurrence of Down Syndrome.
Older paternal age has been linked to an increased risk, although the impact is generally less pronounced than maternal age.
Pregnancies at Any AgeWhile the risk is higher in pregnancies of older women, it’s crucial to note that Down Syndrome can occur in pregnancies of any age.
A significant proportion of babies with Down Syndrome are born to mothers under the age of 35 due to the higher number of births in this age group.
Chromosomal Arrangement ErrorsDown Syndrome can also result from other chromosomal arrangement errors, such as translocation or mosaicism.
Translocation involves part of chromosome 21 attaching to another chromosome, while mosaicism is characterized by a mixture of cells with normal and extra chromosomes. These cases contribute to a smaller percentage of Down Syndrome occurrences.
Environmental FactorsWhile the primary cause is genetic, certain environmental factors may contribute to chromosomal errors leading to Down Syndrome.
Exposure to certain substances or conditions during pregnancy may increase the risk, emphasizing the importance of a healthy lifestyle and prenatal care.
Screening and DiagnosisAdvances in prenatal screening allow for the detection of Down Syndrome during pregnancy.
Screening tests, such as non-invasive prenatal testing (NIPT) and ultrasound, can provide information about the likelihood of Down Syndrome. Diagnostic tests, such as amniocentesis or chorionic villus sampling (CVS), confirm the presence of Down Syndrome and help parents make informed decisions about their pregnancy.

3. Diagnosis and Early Signs of Down Syndrome

Diagnosing Down Syndrome often occurs during pregnancy through prenatal screening tests. Physical signs may include developmental delays, distinctive facial features, and certain health issues.
