Despite being individually rare, inherited rare diseases are collectively common. The diseases we screen for include Cystic Fibrosis, Spinal Muscular Atrophy, Thalassemia, & Tay-Sachs, but there’s more than 100 others that are tested.

Reproductive carrier screening can identify individuals or couples at high risk of having a child with a serious inherited condition. Thus, it is now recommended that carrier screening be offered to all women planning a pregnancy or in the first trimester of pregnancy, regardless of family history or geographic origin.2. It is no substitute for individual inquiry. Compliance with any recommendations does not guarantee discharge of the duty of care owed to patients. Carrier screening is a form of genetic testing that can detect if an individual or couple are carriers of an autosomal recessive and/or X-linked genetic condition, when there is no a priori increased risk based on either partner’s personal or family history.1,9 Involving a simple mouth swab or blood test, it allows a woman or couple to understand their risk of passing an inherited condition on to their children. Genetic carrier screening involves testing healthy individuals (via a blood or saliva sample) for gene mutations that cause diseases that are not present in them. Companies that offer expanded carrier screening create their own lists of disorders that they test for. 0000031796 00000 n The information set out in this publication is current at the date of first publication and is intended for use as a guide of a general nature only and may or may not be relevant to particular patients or circumstances. 0000016543 00000 n Preconception and antenatal carrier screening for genetic conditions: The critical role of general practitioners.

Responsible implementation of expanded carrier screening. While carrier screening was at first offered for one gene at a time, in 2010, a 'universal carrier test' became available, allowing for expanded carrier screening which involves identifying simultaneously the presence or the absence of many gene variants which might be associated with different conditions of varying severity and predictability. Carrier screening does not replace non-invasive prenatal testing (NIPT) and combined first trimester screening (CFTS).
