SMASH™ Genomic Assay

Research applications to accelerate target discovery
and drug development.

Marvel Genomics™ has developed the SMASH Genomic Assay, a Copy Number Variation test that utilizes next-generation sequencing technology and proprietary software. There is great potential for genome sequencing to enhance patient care through improved diagnostic sensitivity and more precise therapeutic targeting. State-of-the-art DNA sequencing technologies and analytical algorithms can be adapted to fit clinical needs. We have focused on optimizing algorithms, giving particular attention to metrics such as reproducibility and accuracy, and standardizing genetic variant calls and interpretation.

Our proprietary approach simplifies DNA sequencing methods and analysis to rapidly identify genetic variants throughout the genome. We have validated samples using SMASH with higher sensitivity and specificity than existing approaches, giving us enhanced capabilities to identify the genetic causes of disease and develop more effective therapeutic molecules.

Clinical Issue/Unmet Needs

Copy number variants, which represent a large component of structural variation in the human genome, consist of duplication or deletion of DNA regions ranging from a few thousand to several million DNA bases in size. CNVs underlie a significant portion of the genetic factors causing autism spectrum disorders (ASD) – work for which Drs. Wigler, Ronemus and colleagues have been at the forefront for over a decade. CNVs have also been shown to play a role in many sporadic disorders such as congenital heart disease, cancer and schizophrenia as well as in patient responses to a variety of therapies.

Marvel Genomics Provides a Solution: SMASH – “Short Multiply Aggregated Sequence Homologies”.

This is a technique optimized for packing multiple independent mappings into every sequence read. The technology increases the information density per read, and it allows massive multiplexing of patient samples with nearly an order of magnitude increase in throughput when compared with whole genome sequencing. As a next-gen sequencing-based method, SMASH™ outperforms Chromosomal Microarray Analysis (CMA) by delivering improved detection of copy number variants: higher resolution, better signal-to-noise and a shorter waiting period between test and results.
