What is FirstScreen (Carrier Screening test)?
FirstScreen is a comprehensive genetic carrier screening test from First Genomix which identifies carriers of genetic conditions. This test scans genes for mutations that cause autosomal recessive and X-linked recessive disorders.
Autosomal recessive disorders (AR)
Arise when a child inherits two mutated copies of the same gene from both carrier parents.
X-linked recessive disorders (XL)
Occur when a mutated gene is located on the X-chromosome. An asymptomatic carrier mother has a 50% chance
of passing the X-linked disorder to her son.
What is the next step following a FirstScreen test?
In case of a positive result, genetic counseling sessions are offered to help couples better-understand their reproductive options.
