GeneDx believes in responsible testing that is based on established medical guidelines, and we aim to be completely transparent with our pricing so that patients, clinicians, and payers know the cost of the test.
Learn about the history of GeneDx and how our unmatched diagnostic testing menu came to be.
Epidermolytic Palmoplantar Keratoderma (EPPK)
Diffuse, yellowish palmar and plantar hyperkeratosis (‘keratoderma’) with a red border. Patients may have blistering in affected areas triggered by trauma, such as friction, however the blistering often appears to improve with age. A rare variant with characteristic electron microscopic findings (“tonotubular keratin”) has been reported in Northern Europe.
Identification of the specific molecular basis of congential ichthyosis or related skin disorders
Genetic counseling and recurrence risk assessment
Option for prenatal testing in future pregnancies
As needed, based on the referring diagnosis and coverage achieved by the XomeDxSlice-Ichthyosis for a given patient, critical exons with a high yield of mutations will be filled-in by dideoxy sequencing. For any autosomal recessive gene, if one definitive mutation is found by XomeDxSlice sequencing, AND the gene fits the type of ichthyosis reported by the referring physician, capillary sequencing will be used to fill in sequence for exons that are not sufficiently covered (>10X) to find the second mutation. If no second mutation is found by sequencing, deletion/duplication analysis of that gene can be performed at no additional cost can be performed at no additional cost.
Patient samples sent for XomeDxSlice will not be evaluated for secondary findings and therefore will not receive secondary findings as part of their result.\\\\\\\\\\\\\\\"
