Familial Mutation Testing: Targeted Sequencing

Condition Description

Genes (0)


Custom DNA sequencing testing is available for any previously characterized DNA variation in a family. 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 call (404) 778-8500 to discuss this testing prior to sample collection.


The region of DNA surrounding the mutation is amplified by PCR and sequenced in both the forward and reverse direction.


Over 99% of previously identified mutations will be detected by this assay.
