There are several cases when genetic testing of a baby might be recommended. Any parents, or parents-to-be, considering embarking down the route of undergoing genetic testing for their baby, either before or after birth, should first consult with a genetic counselor. Meeting with a genetic counselor is important to understand which specific genetic testing might […]
Genetic diagnosis is the process by which the genetic makeup of an individual is examined, to identify or isolate gene or chromosomal changes that might place them at higher risk for developing a rare disease, or confirm a rare disease diagnosis. Genetic diagnosis will generally involve the following steps: Understanding the support and treatment options […]
Inherited diseases are those caused by a gene mutation or chromosomal change that is passed from parent to child during the reproductive process. This DNA change may be passed in one of several different types of genetic inheritance – Autosomal recessive: Autosomal recessive inheritance means an affected individual receives one copy of a mutated gene […]
Genetic testing is a process that involves sampling an individual’s DNA (their genetic makeup), in order to identify gene or chromosomal changes which might impact their health and that of their future children. There are many different types of genetic tests, and each one will involve identifying a specific gene mutation or confirming the presence […]
A genetic disorder may also be referred to as a genetic syndrome, or more commonly a rare disease. There are currently 7,000 and counting genetic disorders identified at present. A genetic disorder may be an inherited condition, where parents pass down gene mutations to their children which then cause a rare disease. Or they may […]
Sibling DNA testing compares the DNA (hereditary genetic material) of two people to see if there is some probability that they are biological siblings (sister or brother). They may be full siblings, half-siblings, or not at all related. Primarily, the goal of sibling DNA testing is to determine or confirm paternity, that is, to see […]
Marfan syndrome is a condition that affects the connective tissue in the body. As this tissue can be found throughout the body, the syndrome can affect multiple parts of the body. The three main parts of the body affected by the syndrome include the ocular system (the eyes), the skeletal system, and the cardiovascular system. […]
Genetic testing for Fragile X syndrome became much more accurate once the specific gene responsible for causing the syndrome, FMR1 was identified. This was then able to replace the chromosome genetic testing which had been the norm before this. This new genetic test, known as either the FMR1 DNA test or the Fragile X DNA […]
It is a form of genetic screening that pregnant women can opt for, usually early in their pregnancy, around the 10th week. As a screening test, it involves the taking of a blood sample from a pregnant woman. The blood of a pregnant woman contains their unborn baby’s DNA in their bloodstream. Cell-free DNA testing […]
