pre-mRNA of collagen type VII alpha 1 chain (COL7A1 pre-mRNA)

The **pre-mRNA of collagen type VII alpha 1 chain (COL7A1)** is a precursor RNA transcript produced from the COL7A1 gene, which encodes type VII collagen, a structural protein essential for anchoring fibrils in the skin's basement membrane zone. Mutations in COL7A1 pre-mRNA can result in aberrant splicing events (e.g., exon skipping, pseudoexon inclusion, cryptic splice site activation), leading to dystrophic epidermolysis bullosa (DEB), a severe blistering skin disorder. Recent therapeutic strategies have targeted the COL7A1 pre-mRNA to correct splicing defects or to allow readthrough of premature stop codons, using approaches such as splice modulation with antisense oligonucleotides, RNA trans-splicing molecules, and readthrough-promoting drugs. Monitoring the correct processing of COL7A1 pre-mRNA and the resultant expression of functional type VII collagen are key biomarkers for therapeutic efficacy.[1][2][3][7]
