Number of Panel Genes20

Connective Tissue Gene Tests 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.

Copy number variation (CNV) analysis of the Recessive osteogenesis imperfecta 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.

Genome Sequencing: A Vital Tool Used in Identifying and Tracking New COVID-19 Variants

Genome sequencing is reading or decoding the complete genetic information i.e. “Genome” of an organism that is encrypted in the form of a very long string called DNA made up of 4 letters, A, T, G, and C. The genome of an organism essentially determines their physical characteristics and ...

The Effect of Genetics on Individual Heart Health: Early Identification of FH Variations to Optimize Treatment

Test must be ordered by a Physician.

Familial hypercholesterolemia (FH) is a genetic disorder that is characterized by abnormally high blood levels of low-density lipoprotein (LDL) cholesterol, sometimes referred to as "bad cholesterol". This condition affects an estimated 1 in 250 people, and increases the likelihood of developing cardiovascular disease. In fact, FH is estimated to be the cause of 2-3% of heart attacks in individuals younger than age 60.
