While the study left researchers with more questions than answers, one thing is certain: this again proves why health equity, which means everyone has a fair opportunity to be healthy, is so important. The center is dedicated to research that identifies disparities like this one.
Researchers in the center are testing ways to reduce disparities and improve health equity so that every child has an equal chance at reaching their best outcomes. If you have a child with Down syndrome and have questions about the care they are receiving, request an appointment with our Down Syndrome Clinic. His specialty clinical interests are Down Syndrome and Neurofibromatosis but sees many rare clinical disorders.
Additionally he is a national expert secondary findings from clinical testing and preventative. However, only about 3 to 4 percent of children with Down syndrome have translocation and only some of them inherited it from one of their parents. When balanced translocations are inherited, the mother or father has some rearranged genetic material from chromosome 21 on another chromosome, but no extra genetic material.
This means he or she has no signs or symptoms of Down syndrome, but can pass an unbalanced translocation on to children, causing Down syndrome in the children. People with Down syndrome can have a variety of complications, some of which become more prominent as they get older. These complications can include:. For people with Down syndrome, getting routine medical care and treating issues when needed can help with maintaining a healthy lifestyle.
Life spans have increased dramatically for people with Down syndrome. Today, someone with Down syndrome can expect to live more than 60 years, depending on the severity of health problems. There's no way to prevent Down syndrome. If you're at high risk of having a child with Down syndrome or you already have one child with Down syndrome, you may want to consult a genetic counselor before becoming pregnant. A genetic counselor can help you understand your chances of having a child with Down syndrome.
He or she can also explain the prenatal tests that are available and help explain the pros and cons of testing. Our patients tell us that the quality of their interactions, our attention to detail and the efficiency of their visits mean health care like they've never experienced.
See the stories of satisfied Mayo Clinic patients. Randi, Simon and Brian Beyerl For new parents of babies born with Down syndrome, the educational brochures that were at their disposal made them feel less than hopeful.
Mayo Clinic's Office of Patient Education knew they could do better, so a team set about creating new materials to provide families with a more optimistic outlook.

Overview The genetic basis of Down syndrome Open pop-up dialog box Close. Diagnosis Down syndrome is usually identified at birth or shortly thereafter.
Cause Down syndrome is usually caused by an error in cell division called nondisjunction. Types of Down Syndrome There are three chromosomal patterns that result in Down syndrome: Trisomy 21 nondisjunction is caused by a faulty cell division that results in the baby having three 21 chromosomes instead of two.
Prior to or at conception, a pair of 21 chromosomes in either the egg or the sperm fails to separate properly. The extra chromosome is replicated in every cell of the body. Ninety-five percent of all people with Down syndrome have Trisomy In translocation a part of chromosome 21 breaks off during cell division and attaches to another chromosome.
The presence of an extra piece of the 21st chromosome causes the characteristics of Down syndrome. Unlike Trisomy 21, which is the result of random error in the early cell division, translocation may indicate that one of the parents is carrying chromosomal material that is arranged in an unusual manner. Genetic counseling can be sought to ascertain more information when these circumstances occur.
Mosaicism occurs when nondisjunction of chromosome 21 takes place in one of the initial cell divisions after fertilization. When this happens, there is a mixture of two types of cells, some containing 46 chromosomes and some The cells with 47 chromosomes contain an extra 21st chromosome. This type of Down syndrome occurs in only one to two percent of all cases of Down syndrome. Health Issues Many children with Down syndrome have health complications beyond the usual childhood illnesses. Prenatal Diagnosis Two types of procedures are available to pregnant women: screening tests and diagnostic tests.
In fact, the average life expectancy for someone with this condition in was 25 years of age compared to 60 years of age in Often, it can be difficult for someone with Down syndrome to receive the same medical care as those without the condition. This is especially true as they age. This makes the role of caregiver so much more important. The good news for those with Down syndrome is that life expectancy is increasing by leaps and bounds. The bad news is that social services and the medical community are lagging.
