These symptoms result from variations in the <jats:italic>FERMT1<\/jats:italic> gene (Fermitin family member 1, OMIM: 607900), encoding kindlin-1, an essential component of focal adhesions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>This study aims to ascertain the potential pathogenicity of a <jats:italic>FERMT1<\/jats:italic> variant identified in a Chinese patient and to explore the phenotypic and molecular genetic characteristics of all reported cases of Kindler Syndrome in the Chinese population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Whole-exome sequencing (WES) was performed on the patient to identify candidate variants associated with KS, and Sanger sequencing was utilized to authenticate their presence and origin. To further assess the potential impact of these genetic variants, we employed a variety of in silico prediction tools. Concurrently, a review of various databases was undertaken to ascertain and consolidate information regarding cases of KS in Chinese families.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We identified a novel likely pathogenic frameshift variant in the <jats:italic>FERMT1<\/jats:italic> gene, specifically c.567_579delTATATATGACCCC (p.Ile190Serfs*10). The clinical presentation of this patient aligns with the diagnostic criteria for KS. The literature review reveals that the core clinical features of KS reported in the Chinese population include skin abnormalities (100%), as well as hyperkeratosis of the palms and soles (91.70%). Other clinical phenotypes encompass nail abnormalities (77.78%), abnormalities of the fingers\/toes (75.00%), oral damage (70.00%), eye abnormalities (57.14%), and constipation (50.00%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our study enriches the genetic landscape of KS in the Chinese population and augments the understanding of phenotypic variability resulting from <jats:italic>FERMT1<\/jats:italic> gene variants.
