Carrier screening test by OneDNA helps identify inherited genetic risks before pregnancy, enabling informed family planning and reducing chances of passing conditions.
Carrier screening is a genetic test that identifies individuals who carry pathogenic variants associated with autosomal recessive disorders. Carriers are typically asymptomatic, as they possess one normal and one mutated allele. However, if both partners carry variants in the same gene, there is a 25% risk in each pregnancy of having an affected child, making carrier screening essential for accurate reproductive risk assessment and informed decision-making.
