Accelerate your diagnosis with rapid clinical variant prototyping
- We provide information about your patient’s exact genetic allele in a whole organism context to help you decide what to do next
- We perform Clinical Variant Phenotyping using precision humanization of model systems to:
- Assign pathogenicity status to patient alleles.
- Identify therapeutic agents for reversing pathogenicity.
We can help you answer the following questions:
- What is the outcome of my patient’s specific genetic mutation?
- How can I help a patient with an allele that hasn’t yet been characterized?
- Can I determine potential treatment options for my patients with genetically linked diseases?
How it works
- Humanize an organism with the specific human gene and insert your allele of interest.
- Create appropriate control strains
- Confirm all strains via sequencing and other QC
- Assess transgenic strain(s), wild type(s), and controls using one or more phenotypic assays
Quantitative Analysis delivered to you:
- Transgenic vs. control data for each assay, including statistical significance.
- Comparison of transgenic vs. control overall, combining all assay scores. This single number can be used to quickly benchmark overall gene function.
See the sample report below.
We can also perform drug testing on strains of interest.

Variants of Uncertain Significance (VUS allele)
Genomic discoveries have revolutionized biomedical research. Clinicians now routinely use genomic data to decide treatment options. Yet genomic complexity creates a challenging problem – each person has 100s of gene variations that may or may not have a known association with a disease. These individual genetic differences (a person’s genotype) can have a profound effect on a person’s physiology (phenotype). A majority of the genomic differences found in individuals are currently classified as Variants of Uncertain Significance (VUS allele).
This classification is needed for its ability to guide individualized patient therapy. Computational approaches are also a valuable tool, but definitive findings require the in-vivo gene function assessment provided through phenotypic analysis.
