Genetic variants in vascular disease genes were found in patients with multiple arterial aneurysms. Whole exome sequencing (WES) can help identify these germline variants for improved clinical management.
Area of Science:
- Genetics
- Vascular Biology
- Medical Diagnostics
Background:
- Multiple arterial aneurysms can indicate underlying genetic predispositions.
- Identifying causal genetic variants is crucial for understanding disease mechanisms and improving patient care.
Purpose of the Study:
- To identify causal genetic variants in patients presenting with multiple arterial aneurysms.
- To explore the genetic basis of arterial aneurysm formation in a selected patient cohort.
Main Methods:
- Whole exome sequencing (WES) was performed on nine patients with multiple arterial aneurysms.
- Candidate variants were selected based on in silico predictions and filtered against gnomAD allele frequencies.
- GeneCards and MalaCards databases were used to correlate variants with vascular diseases.
Main Results:
- Twenty-four variants in 23 different genes associated with vascular diseases were identified.
- Specific variants were found in SMAD3 (associated with Loeys-Dietz syndrome 3), TNXB (associated with Ehlers-Danlos syndrome), and TET2/PPM1D (associated with CHIP).
- All nine patients carried variants in genes linked to vascular diseases, though pathogenicity requires further investigation.
Conclusions:
- Patients with multiple arterial aneurysms harbor variants in vascular disease-associated genes.
- Further research is needed to understand the pathogenicity of identified variants.
- Whole exome sequencing (WES) is recommended for patients with multiple arterial aneurysms to guide clinical management.

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
