Test Code
C5069
Test Name
Ehlers-Danlos - Syndrome NGS Panel Dominant & Recessive
CPT Codes
81479
Expected Turnaround Time
Typically 2 to 4 weeks from receipt of a sample in the laboratory. All cases involving ongoing pregnancies will be expedited.
Clinical Utility
Genetic analysis to provide a molecular diagnosis of Ehlers-Danlos syndrome (EDS). EDS is a connective tissue disorder characterized by joint hypermobility, skin hyperextensibility and tissue fragility. There are numerous subtypes of EDS each with distinct genetic and clinical findings. Recommended for individuals with a personal and/or family history of Ehlers-Danlos syndrome to ensure appropriate treatment and establish recurrence risk for family members.

Description

The dominant & recessive Ehlers-Danlos syndrome NGS panel is designed to detect mutations in genes that cause clinical features related to Ehlers-Danlos syndrome (EDS). EDS is a connective tissue disorder characterized by joint hypermobility, skin hyperextensibility and tissue fragility. There are numerous subtypes of EDS each with distinct genetic and clinical findings. Genomics offers several panel options for Ehlers-Danlos syndrome testing including a classic type panel, a core panel, a dominant panel, a recessive panel and a combined dominant and recessive panel. In addition to genes associated with the dominant and recessive forms of EDS, the panels also contain genes for disorders included in the differential diagnosis of EDS.
