GALEAS™ Hereditary PlusA clinically validated NGS panel with optimized bioinformatics for analyzing germline mutations associated with hereditary cancers - including Lynch syndrome.
Complete hereditary cancer analysis at your fingertips. Streamline your testing from sample to data analysis.
Between 5 and 10% of all cancers1, including those of the breast, ovary, uterus, prostate, and gastrointestinal system can be accounted for by hereditary cancers.
Genetic testing plays a crucial role in identifying individuals who have inherited variants within cancer susceptibility genes and are at increased risk of developing hereditary cancer. This information is invaluable for guiding screening, personalized treatment and preventive strategies aimed at improving the survival and outcomes for individuals.
Multi-gene next generation sequencing (NGS) panels have emerged as a widely accepted and clinically viable option for the diagnosis of hereditable cancers. However, many targeted NGS panels struggle to identify key hereditary cancer CNVs and require additional multiplex ligation dependant probe amplification (MLPA) analysis to detect them limiting their usefulness in testing.
With its complete scope, including the detection of single nucleotide variants (SNVs), insertions and deletions (indels) and a wide range of copy number variants (CNVs), GALEAS HereditaryPlus combines an innovative NGS panel with optimized bioinformatics to offer a viable option for reducing costly and time consuming MLPA and ensure unparalleled precision in hereditary cancer testing.

GALEAS HereditaryPlus is an innovative Next Generation Sequencing (NGS) panel that includes a meticulously curated collection of 146 genes well-established in their associations with hereditary cancer. The targeted gene list addresses not only key cancer syndromes like Lynch syndrome but also covers rarer hereditary cancer types like Phaeochromocytoma and pediatric cancers like Wilms tumor, ensuring a comprehensive understanding of the genetic landscape. The ability to target many types of cancer in one assay enables laboratories to streamline hereditary testing workflows.
GALEAS HereditaryPlus offers unparalleled variant detection in hereditary cancer analysis
The combination of careful design and state of the art bioinformatics pipelines supports the accurate detection of SNVs, indels and a wide range of CNVs without the need for additional testing with Sanger sequencing or Multiplex Ligation-dependent Probe Amplification (MLPA) analysis. This innovative NGS panel provides unparalleled precision in hereditary cancer analysis regardless of variant type or cancer type.
SNVs: Delivers reliable identification of SNVs including direct genotyping of the MSH2 c.942+3A>T variant avoiding the need for Sanger sequencing and streamlining testing workflows.
INDELs: Accurately detects both small and large indels, including those exceeding 10 base pairs.
CNVs: Reliably and robustly identifies CNVs from single exons to whole genes and mosaic copy number variation potentially eliminating the need for MLPA in hereditary cancer testing.
With GALEAS HereditaryPlus, laboratories can trust in exceptional accuracy and reliability of variant detection across a wide range of alteration types. Our commitment to innovation and precision empowers clinicians to make informed decisions and provide personalized care to individuals at risk of hereditary cancer.

Overcoming Challenges: CNVs, mosaics and pseudogenes
While many NGS panels excel at detecting SNVs and small indels, accurately identifying CNVs associated with hereditary cancer presents a significant challenge and often requires the use of ancillary tests like MLPA to detect them reliably.
GALEAS HereditaryPlus combines an expertly constructed CNV probe design with optimized bioinformatics pipelines to enable laboratories to
Confidently call PMS2 gene variants.
In a clinical study of 64 patients with orthogonal data, GALEAS HereditaryPlus delivered an analytical sensitivity of 98.3% and an analytical specificity of 99% for CNV analysis. This high level of sensitivity and specificity guarantees the identification of critical genetic alterations associated with hereditary cancer, empowering clinicians with actionable information for disease management.
