Overview


Minagene offers advanced genetic testing for Fragile X Syndrome, a genetic disorder characterized by intellectual disability and various physical and behavioral features. Our comprehensive Fragile X Syndrome genetic testing service provides valuable insights into the underlying genetic factors contributing to the condition, enabling accurate diagnosis, personalized care plans, and improved outcomes for affected individuals and their families.


Methodology



Understanding Fragile X Syndrome


Fragile X Syndrome is a genetic disorder caused by an expansion of the CGG triplet repeat sequence in the FMR1 gene. This expansion leads to a deficiency or absence of the Fragile X Mental Retardation Protein (FMRP), which plays a crucial role in brain development and function. Fragile X Syndrome is the most common inherited cause of intellectual disability and is more frequently observed in males than females.


The Importance of Genetic Testing


Genetic testing plays a critical role in the accurate diagnosis and management of Fragile X Syndrome. By identifying the CGG repeat expansion in the FMR1 gene, genetic testing confirms the diagnosis and helps assess the risk of passing the condition to future generations. It also enables early interventions, personalized care plans, and access to appropriate support services for affected individuals and their families.

Overview


Whole Exome Sequencing (WES) is a genomic test that examines the complete coding region of the genome, including all coding regions and splice junctions. Unlike targeted gene panels, WES analyzes variations in the protein-coding region of any gene, offering a broader scope for identifying disease-causing mutations. Since most known disease-causing mutations occur in exons, WES is often more effective than whole genome sequencing.


Methodology



Next Generation Sequencing (NGS)


Genomic DNA extracted from blood is used to simultaneously capture and sequence the coding regions of all genes on an Illumina platform. The resulting sequence data is then aligned and analyzed to identify sequence variants.


Key Highlights of the Test:
