Prenatal testing: Targeted sequencing
Test Code: 856875P
Turnaround time: 2 weeks
Custom DNA sequencing for any previously characterized pathogenic or likely pathogenic DNA variation in a family. To perform this assay we require details of the genetic variation in the family. Please contact CEN4GEN first to discuss this testing prior to sample collection.
The region of DNA surrounding and including the mutation is sequenced.
Analytical sensitivity: 99%
CEN4GEN requires a blood sample from the mother, as well as a fetal sample.
As far as fetal sample requirement (other than fetal blood):
Direct chorionic villus sampling (CVS), at least 10 mg is needed.
For direct amniocentesis, at least 10 ml is needed.
For cultured chorionic villus sampling (CVS) or amniocytes, two T-25 flasks are needed.
Type: Whole Blood from mother
In EDTA (purple top) or ACD (yellow top) tube: 5 ml
Specimen Collection and Shipping: Ship sample at room temperature with overnight delivery (if possible).
