SPINK5 (LEKTI)
Genetic findings for SPINK5 (LEKTI) in Chronic Rhinosinusitis with Nasal Polyps
Variants (1)
| Variant | Type | Frequency | Significance |
|---|---|---|---|
| Missense and regulatory variants | germline | Candidate gene association | SPINK5 encodes a serine protease inhibitor critical for epithelial barrier integrity. Variants lead to increased protease activity and barrier disruption. |
Clinical implications
Missense and regulatory variants
Supports epithelial barrier defect as primary pathogenic event.
