Description

Genomics offers five panel options for osteogenesis imperfecta (OI) testing utilizing NextGen sequencing technology, an OI COL1A1 & COL1A2 panel, an OI core panel, a dominant OI panel, a recessive OI panel and a combined dominant and recessive OI panel. In addition to genes associated with the autosomal dominant and autosomal recessive forms of OI, the panels also contain genes for disorders included in the differential diagnosis of OI. 

The Recessive osteogenesis imperfecta panel consist of twenty genes: ALPL, BMP1, CREB3L1, CRTAP, FKBP10, LRP5, MBTPS2, P3H1, PLOD2, PLS3, PPIB, SEC24D, SERPINF1, SERPINH1, SP7, SPARC, TAPT1, TMEM38B, WNT1 and XYLT2.
