They can be subclassified into syndromic and nonsyndromic forms. Syndromic ichthyoses affect organs beyond the skin. An increasing number of causative genes has been identified.</p><p><strong>Objectives: </strong>To identify the causative gene and the underlying pathogenesis of a previously unreported syndromic ichthyosis.</p><p><strong>Methods: </strong>Whole-exome sequencing (WES), combined with Sanger sequencing, was utilized to identify the genetic defect. Protein structural modeling and dual-luciferase reporter assays were employed to investigate the effects of the pathogenic variants on KLF4. A human embryonic stem cell-H9 line (hESC-H9) harboring the pathogenic variant was developed into a skin organoid for morphological observation and RNA sequencing analysis. The expression of candidate target genes was further validated in patients' skin samples using quantitative RT-PCR and immunofluorescence.</p><p><strong>Results: </strong>We collected four unrelated sporadic patients with a syndromic ichthyosis, predominantly manifesting as ichthyosis, palmoplantar keratoderma, hypotrichosis, periorificial keratosis, nail dystrophy, and varying extracutaneous involvement. WES identified two heterozygous missense variants, c.1322A>G (p.Asp441Gly) and c.1323T>A (p.Asp441Glu), in the KLF4 gene in these patients. Protein modeling predicted that the substitutions of the affected residue, Asp441, were likely to affect the stability of the local α-helix structure. Both variants exhibited reduced transcriptional activity. Skin organoids derived from hESC-H9 cells harboring the heterozygous c.1323T>A variant displayed defects in epithelial morphogenesis and abnormal expression of keratinocyte differentiation-related genes and WNT signaling genes. Decreased expression of KLK7 and WNT10A, which are vital for skin desquamation and multi-organ development, respectively, was detected in the patients' skin lesions.</p><p><strong>Conclusions: </strong>Loss-of-function variants affecting residue Asp441 of KLF4 cause an autosomal dominant syndromic ichthyosis with multi-organ involvement. These variants impair KLF4 transcriptional activity, leading to the downregulation of multiple genes, particularly KLK7 and WNT10A.
