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.

Sjogren Larsson Syndrome (SLS)
Sjögren Larsson Syndrome manifests with congenital ichthyosis with generalized but variable distribution and quality in the first year of life. The skin is frequently very pruritic. Other characteristic features are delayed motor development due to spastic diplegia or tetraplegia, mental retardation, speech delay, short stature, and seizures. “Glistening white dots” on the retina and pigmentary retinal degeneration are found in about one-third of patients.
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.\\\\\\\"
