MPRA functional analysis of 44 SNVs — identification of a functional intronic SNV in VCAN (enhancer modulation, mRNA impact)
Summary
MPRA functional characterization of 44 SNVs previously GWAS-associated with cerebral small vessel disease, spread across 9 candidate genes. The study identifies a functional intronic SNV in VCAN that modulates an enhancer, providing evidence of a direct molecular contribution of Versican to CSVD and illustrating the transition from GWAS association to functional proof.

Analysis
Methodological showcase (GWAS → MPRA → functional variant) transposable to other phenotypes. Disease not strictly monogenic but with a genetic component — may be of interest in early-onset familial CSVD.
