GT HapScreen® DMD

SKU: GT-11204 Categories: ,

Duchenne Muscular Dystrophy (DMD) is the most common childhood form of Muscular Dystrophy. GT Hapscreen DMD is for segregation analysis for DMD and BMD. Using with MLPA or sequencing, gives more accuracy to PND and carrier detection, plus more benefits.

GT HapScreen® DMD

For more accurate and risk free prenatal diagnosis of DMD/BMD

Duchenne Muscular Dystrophy (DMD) is the most common childhood form of Muscular Dystrophy. It affects 1 in 3500 - 5000 boys. The milder form of the disease is called Becker Muscular Dystrophy (BMD). The disease is inherited as X-linked recessive; so, it is predominantly seen in males. The gene responsible for the disease is called Dystrophin, which is one of the largest genes expanding over 76 exons on the short arm of the X-chromosome. DMD is predominantly caused by deletion or duplication, though point mutation is also seen in about 30% of cases. DMD in about 30% of the cases is caused by a new mutation. This makes the diagnosis even more challenging.

Prenatal diagnosis (PND) for inherited disorders have become a routine practice. Millions of PNDs are performed each year worldwide. Molecular prenatal detection is of crucial importance since most of the PNDs are carried out using this procedure. PND is prone to misdiagnosis for various purposes including maternal cell contamination, sample mix-up, sample contaminated with other samples, gonadal mosaicism, etc. The advent of Next Generation Sequencing (NGS) has enabled us to better detect the molecular basis of many inherited disorders including DMD. Some of these disorders are more prevalent in some parts of the world or some specific ethnicities (such as beta-thalassemia, H-disease, Sickle cell disease, and cystic fibrosis), however; the incidence of DMD/BMD is somewhat similar worldwide.

The GT HapScreen® DMD kit has been developed to detect carriers or affected individuals for DMD/BMD. The kit functions based on STR markers and QF-PCR technique to detect carriers as well as fetal samples by linkage or segregation analysis. Use of STR markers makes prenatal diagnosis more accurate, more reliable and less prone to common errors.

Kit components include multiplex PCR primers which are designed flanking the dystrophin gene. This gene is investigated in carrier detection and prenatal diagnosis of Duchenne or Becker Muscular Dystrophies. STR markers designed from 6 regions that cover the upstream, downstream and intron of the dystrophin gene. This kit is optimized to use DNA samples purified from blood, amniotic fluid, chorionic villus (CVS), or direct sample to PCR using any of the following lysis buffers GT BLB, GT AFLB and GT CVLB.

Along with Duchenne or Becker Muscular Dystrophy detection, the GT HapScreen® DMD kit includes autosomal STR markers used for QF-PCR to detect aneuploidies of chromosomes 21, 18, 13, X and Y as well as many other advantages outlined in the introduction section of GT HapScreen® kits. These markers provide extra advantages along with the detection of diseases.

GT HapScreen® DMD kit panel. As can be seen there are 6 Dystrophin gene linked STR markers and an extra STR marker on the X-chromosome (DXS6803) as well as the AMXY. The kit also contains 3 STR markers for chromosome 21, 2 for chromosome13 and 2 for chromosome 18, in total 15 markers in a 5-dye system. This kit can be used for confirming prenatal diagnosis, carrier detection and confirmation of NGS results. For information on what is the technology behind GT HapScreen® please click here or go to
