Genetic carrier screening

Carrier screening looks for gene changes that cause recessive conditions — a carrier is healthy, but if both partners carry a change in the same gene there is a chance of an affected child. Screening choices are often guided by family history and background. Results are best interpreted with genetic counselling, and options such as PGT-M may be discussed if both partners carry the same condition.
