Genetic clues for lichen sclerosus in families
Official title: Identification of Genetic Variants Associated With Lichen Sclerosus
Run by Medbase · NCT07720830 · Data updated 2026-11-12
Researchers will look for genetic variants linked to lichen sclerosus by sequencing the genomes of affected families to see which genes might contribute to the condition.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals with clinical or histological confirmation of lichen sclerosus and willing family members who have or have not been affected by LS.
✕Probably not a fit
Participants without informative family history or lacking affected relatives may have limited likelihood of contributing to genetic discoveries.

What this trial studies
This observational study aims to identify genetic variants associated with lichen sclerosus by sequencing exomes or genomes in families where some members are affected and others are not. The approach is exploratory and focuses on segregation of variants within pedigrees to uncover potential Mendelian genes. There are no interventions or clinical endpoints; success is defined by discovery of novel LS-related genes through family-based sequencing. Enrollment prioritizes families with multiple affected individuals to increase the chance of finding meaningful genetic associations. The study is conducted at Medbase in Frauenfeld with collaborating centers involved in the analysis.
Why it matters
Potential benefit: If successful, the study could reveal genetic factors that contribute to lichen sclerosus and guide future research into targeted diagnostics or therapies.
How similar studies have gone: Prior research has shown that family-based sequencing can identify genes associated with complex skin conditions, though this exact approach for LS is exploratory.
