Genes and Diseases eyeGENE®
The genes and diseases currently being tested by the eyeGENE® Network are given in the table below. The eyeGENE® Working Group, which includes ophthalmologists and genetic counselors, determines the genetic tests that are ordered upon the review of the clinical data submitted by the referring health care provider. At any point in the process, the referring health care provider is welcome to confer with his/her NEI professional colleagues.

^ Limited to 50 tests per yr; Participants' samples will be tested in the order they are received. Please contact the eyeGENE® Coordinating Center for more details.
*In individuals of Puerto Rican decent - test screens for a 16 bp duplication in HPS1 and a 3.9 kb deletion in HPS3.
Ashkenazi Jewish individuals will be tested for IVS5 splice site mutations in HPS3 only. HPS samples from individuals outside of these categories will not be tested at this time.
**not all genes sequenced in full and not all are available outside of panel
Genetic tests ordered are determined by the eyeGENE® Working Group after review of the clinical data submitted by the referring clinician.
Sporadic/isolated and recessive retinitis pigmentosa and sporadic/isolated and recessive Cone-Rod Dystrophy
At the present time, patient samples will be collected and stored in the eyeGENE® repository and NOT CLIA-tested. Although some tests are available, careful systematic diagnostic assays are cost prohibitive to the eyeGENE® Network at this time. These stored samples will be CLIA-tested once new CLIA-approved diagnostic technology is available through the eyeGENE® Network. Potential results may become available through research screening. Individual level genetic results from research will be confirmed in a CLIA- approved diagnostic laboratory before being communicated.
