One Known Familial Variant in a Nuclear Gene

Forms and Documents


Test Details

  • Carrier testing for a specific variant previously identified in a family.
  • Clinical laboratory confirmation of one variant identified in a research laboratory.
  • If you would like to order a targeted testing of two variants in the same gene please use test code 9012.
  • For specimens drawn in New York, carrier or targeted variant testing is an approved test if the family had previous testing at GeneDx or if the gene itself is in an approved single-gene test or multi-gene panel: NY Test List. In these situations it is not necessary to obtain individual NYSDOH permission.

GeneDx does not currently offer targeted prenatal testing for variants found in Mitochondrial (mtDNA) genes.
