Clinical Trial Summary

The goal of this study is to identify and characterize novel non-coding and splicing variants that may contribute to genetic disorders. We will particularly focus on patients with a diagnosed genetic disorder that has inconclusive genetic findings.

Description:

To perform this study, we will use patient DNA and RNA that is isolated from blood samples. DNA will be sequenced (targeted capture and/or whole genome DNA sequencing (WGS)) to identify any non-coding single nucleotide variants (SNVs), smaller insertions/deletions (indels), or larger structural variants (SVs). RNA will be sequenced (RNA-seq) to identify genes that are expressed in a differential and/or allele-specific manner, which may indicate a functional non-coding or splicing variant. We will test the function of non-coding variants using high-throughput reporter assays and CRISPR based methodologies.
