The Horizon carrier screening offered by Natera analyzes parental DNA to assess the risk of a child inheriting specific genetic conditions. This screening examines numerous genes associated with autosomal recessive and X-linked disorders, providing prospective parents with information to make informed reproductive decisions. For instance, the analysis might reveal if both parents carry a mutation for cystic fibrosis, indicating a 25% chance of their child inheriting the condition.
Such advanced genetic screening plays a crucial role in family planning, offering proactive insights into potential hereditary health risks. Historically, carrier screening was limited to a few common conditions, but technological advancements now permit broader analyses encompassing a wider range of disorders. This expanded scope facilitates more informed decision-making regarding reproductive options, such as in-vitro fertilization with preimplantation genetic testing or pursuing alternative family-building pathways.
