Description of intervention(s) / exposure
Other interventions - Reproductive Genetic Carrier Screening

Experimental: Participating Couples - Reproductive Genetic Carrier Screening


Other interventions: Reproductive Genetic Carrier Screening
Carrier screening for approximately 1300 genes associated with severe autosomal recessive and X-linked recessive conditions affecting children will be performed on each member of the couple. A combined result will be issued indicating whether the couple has a 'low' or 'increased' risk of having a child with a genetic condition

Eligibility
Key inclusion criteria
In order to take part in the study, couples need to have visited a recruiting HCP who will assess them for eligibility based on the criteria below:

INCLUSION CRITERIA

* Planning to become pregnant or in early pregnancy (less than 10 weeks gestation at enrolment and less than 11 weeks gestation at sample receipt by the laboratory)
* Both members of the couple available to participate in the study and available to provide a sample for testing at the same time.
* If the couples are using an egg/sperm donor/s, the donor/s need to be available to provide a DNA sample for testing and consent to having carrier screening.

NB: If both members of the couple are known carriers of the same autosomal recessive condition, or the female is a known carrier of an X-linked recessive condition, they will still be eligible to have RGCS through the study, but will only be considered an 'increased-risk' couple for the purposes of this study if they are identified through the study testing to be carriers of pathogenic variants in a different gene.

EXCLUSION CRITERIA

Participating couples meeting any of the following requirements will be excluded from this study:

* Pregnant and greater than 10 weeks gestation at enrolment.
* Only one member of the couple agrees to participate in the study.
* One or both members of the couple are less than 18 years old.
* Both members of the couple are not available to be tested at the same time.
* The couple are using an egg/sperm donor/s and the donor/s are not available for testing or the couple are using an anonymous donor.
* One member of the couple has already been screened as part of the study.
