Familial Mutation Testing: Targeted Deletions/Duplications
Test Code: 2330
Turnaround time: 3 to 4 weeks
Known mutation testing for a specific deletion or duplication is available for those genes for which we offer full gene del/dup testing. (Please see our test menu for a list of genes for which del/dup testing is offered.) This service can also confirm DNA variations identified in a research laboratory. Such confirmation allows release of research findings to the patient as well as prenatal diagnosis and carrier testing for other at-risk family members. To perform this assay we require details of the genetic variation in the family and a DNA sample from a previously tested individual as a positive control. Please contact CEN4GEN first to discuss this testing prior to sample collection.
DNA isolated from peripheral blood is hybridized to a CGH array to detect deletions and duplications.
Over 99% of previously identified mutations will be detected by this assay.
