Epidermolysis bullosa NGS panel

Number of Panel Genes:

Epidermolysis bullosa (EB) is a clinically and genetically heterogeneous group of mechanobullous diseases. They are characterized by skin fragility with recurrent blister formation. EB can be divided into four major types: EB simplex, junctional EB, dystrophic EB and Kindler. Peeling skin syndrome is also included in this panel.

The Epidermolysis bullosa NGS panel consists of twenty-four genes: CAST, CDSN, CHST8, COL17A1, COL7A1, CSTA, DSP, DST, EXPH5, FERMT1, ITGA3, ITGA6, ITGB4, JUP, KLHL24, KRT5, KRT14, LAMA3, LAMB3, LAMC2, PKP1, PLEC, SERPINB8, and TGM5.

Copy number variation (CNV) analysis, of the epidermolysis bullosa genes, is also offered as a panel. Additionally, CTGT offers a comprehensive test (both NGS and CNV panels) for these genes. Panel genes are also offered as individual sequencing and deletion/duplication tests unless otherwise indicated.
