How many people have edwards syndrome

The numbers of total births is much higher because it includes significant numbers of stillbirths that occur in the 2nd and 3rd trimesters of pregnancy. Unlike Down syndrome, which also is caused by an extra chromosome, the developmental issues caused by Trisomy 18 are associated with more medical complications that are more potentially life-threatening in the early months and years of life. Again, baby boys will experience higher mortality rates in this neonatal period than baby girls, although those with higher birth weights do better across all categories.

Some infants will be able to survive to be discharged from the hospital with home nursing support to assist with care by the parents. A small number of babies with Edwards' syndrome about 1 in 20 have an extra chromosome 18 in just some cells.

This is called mosaic Edwards' syndrome or sometimes mosaic trisomy This can lead to milder effects of the condition, depending on the number and type of cells that have the extra chromosome. Most babies with this type of Edward's syndrome who are born alive will live for at least a year, and they may live to adulthood. A very small number of babies with Edwards' syndrome about 1 in have only a section of the extra chromosome 18 in their cells, rather than a whole extra chromosome This is called partial Edwards' syndrome or sometimes partial trisomy How partial Edwards' syndrome affects a baby depends on which part of chromosome 18 is present in their cells.

Edwards' syndrome is associated with certain physical features and health problems. Every baby is unique and will have different health problems and needs. They will usually have a low birthweight and may also have a wide range of physical symptoms.

They may also have heart, respiratory, kidney or gastrointestinal conditions. Despite their complex needs, children with Edwards' syndrome can slowly start to do more things.

If you're pregnant, you'll be offered screening for Edwards' syndrome between 10 and 14 weeks of pregnancy. This looks at the chance of your baby having the condition. This screening test is called the combined test and it works out the chance of a baby having Edwards' syndrome, Down's syndrome and Patau's syndrome. During the test you'll have a blood test and an ultrasound scan to measure the fluid at the back of your baby's neck nuchal translucency.

If it's not possible to measure the fluid at the back of your baby's neck, or you're more than 14 weeks pregnant, you'll be offered screening for Edwards' syndrome as part of your week scan. This is sometimes known as the mid-pregnancy scan. It's an ultrasound scan that looks at how your baby is growing. Screening cannot identify which form of Edwards' syndrome your baby may have, or how it will affect them.

If the combined test shows that you have a higher chance of having a baby with Edwards' syndrome, you'll be offered a test to find out for certain if your baby has the condition. This diagnostic test involves analysing a sample of your baby's cells to check if they have an extra copy of chromosome These are invasive tests that increase your chance of having a miscarriage. Your doctor will discuss this with you.

A specialist doctor obstetrician or midwife will explain what the screening results mean and talk to you about your options. This is a very difficult situation and it's normal to feel a whole range of emotions. Trisomy 18 or Edwards syndrome is a chromosomal disorder that causes severe disability. Most babies with trisomy 18 die in the first weeks of life.

Amniocentesis is a diagnostic test carried out during pregnancy to assess whether the baby has an abnormality or serious health condition. A nuchal translucency scan is part of the ultrasound scan that may give an indication of chromosomal abnormality.

Learn more about how and when it is performed. The principle of screening is to offer a safe, accessible test to identify women with an increased chance of having a baby affected by a chromosomal or genetic condition. A non-invasive prenatal test NIPT is a sensitive test to screen for Down syndrome and some other chromosomal disorders in the first trimester of pregnancy.
