KRT6A Variant Underlies Pachyonychia Congenita: Insights Into Protein Aggregation and PPAR Signaling.
Variants in the keratin 6A (KRT6A) gene are a major cause of pachyonychia congenita (PC), a rare autosomal dominant disorder characterized by nail hypertrophy and other ectodermal abnormalities. This study aimed to identify the causative mutation in a PC family and investigate the underlying pathogenic mechanism. We performed exome sequencing on this PC pedigree and validated candidate variations using Sanger sequencing. In silico predictions and in vitro experiments showed that the heterozygous missense variant c.512A>G in KRT6A was pathogenic, inducing protein aggregation and disrupting filamentous network structures. Enrichment analysis suggested that the PPAR signaling pathway played a crucial role in PC, with decreased expression of PPARβ/δ in HeLa cells. Comparative analysis of PC patients carrying the p.Asn171 variant revealed marked heterogeneity in clinical manifestations. Notably, oral leukokeratosis, a common phenotype in KRT6A mutation carriers, was not observed in the patients in this study. Interestingly, one patient presented with small papules around the lips and nasal bridge. We conclude that the c.512A>G variant in KRT6A is the genetic cause of this PC family, diagnosed as PC-K6a subtype. This study expands the phenotypic spectrum of congenital PC and suggests the PPAR signaling pathway as a potential therapeutic target.
Functional roles of Keratin 6A in disease pathogenesis across cancer and skin disorders.
Keratin 6A (KRT6A) is an epithelial-specific type II keratin localized within cytoskeletal intermediate filaments and functions in cooperation with KRT16/17 to maintain epidermal homeostasis and tissue repair. Accumulating evidence highlights its multifaceted roles in cancer. Aberrant KRT6A expression promotes cell cycle progression, epithelial-mesenchymal transition, migration, and invasion, thereby driving tumor initiation and metastasis, although tumor-suppressive effects have been observed in specific contexts. Mechanistically, KRT6A regulates adhesion, cytoskeletal remodeling, and critical signaling pathways, thereby reshaping tumor immunity and metabolism to facilitate immune evasion and metabolic dysregulation. Elevated KRT6A expression is strongly associated with resistance to chemotherapy, targeted therapy, and radiotherapy. Therapeutic approaches targeting KRT6A include nucleic acid-based interventions, protein degradation strategies, inhibition of upstream regulatory pathways, and combinatorial regimens to overcome drug resistance. Clinically, KRT6A has emerged as both a diagnostic and prognostic biomarker, supporting treatment monitoring and enhancing predictive models for risk stratification and individualized outcome evaluation. Beyond oncology, mutations in KRT6A underlie pachyonychia congenita, and its dysregulation contributes to epidermal hyperproliferative disorders such as psoriasis. Overall, systematic elucidation of the structure-function-pathway-clinical axis of KRT6A offers new opportunities for precision medicine and supports its potential as a therapeutic target in cancer management.
Proteomics reveals altered lipid biosynthesis and keratin hyperphosphorylation in pachyonychia congenita.
Pachyonychia congenita is a rare and painful skin disorder caused by dominant pathogenic variants in keratin genes (K6A/K6B/K6C/K16/K17), with no effective treatment. We developed a scalable, in-depth, and miniaturized mass spectrometry-based proteomics and phosphorylated proteomics analysis of full-thickness skin biopsies applied to 10 patients with pachyonychia congenita to elucidate pathogenic mechanisms and pinpoint therapeutic targets. We quantified 7200 protein groups on average from 2-mm snap-frozen skin samples, the most in-depth proteome coverage reported to date from a single-shot mass spectrometry analysis. Among the identified protein groups, ∼1400 proteins were differentially abundant in lesional versus nonlesional samples. Enrichment analysis points toward impaired mitochondrial function, hyperkeratinization, enhanced immune response, and a significant increase in cholesterol biosynthesis. Phosphoproteomics revealed hyperphosphorylation of specific sites in pachyonychia congenita-related keratins; confirmed the hyperactivation of EGFR and downstream kinases, including protein kinase C and Src, and disclosed p38 MAPK activation. All of these kinases have been reported to phosphorylate keratins. Our study expands upon current understanding of the consequences of EGFR pathway activation, including increased cholesterol biosynthesis, thereby renewing interest in the use of statins for pachyonychia congenita. Above all, it provides a solid foundation for the continued exploration of EGFR inhibitors and offers therapeutic avenues, particularly those using multikinase inhibitors.
Early-onset Pachyonychia Congenita with Oral and Cutaneous Manifestations.
An 11-year-old girl presented with painful plantar hyperkeratosis and nail dystrophy, evident since infancy. Examination revealed hyperkeratotic plaques on the soles, wedge-shaped nail hypertrophy, follicular hyperkeratosis over the extremities, and oral leukokeratosis. A positive maternal history suggested autosomal dominant inheritance with variable expressivity, consistent with pachyonychia congenita. Fungal infection was excluded via KOH mount; genetic testing was unavailable due to financial constraints. Despite prior treatments with keratolytics and emollients, improvement was minimal. This case highlights the early onset, classical features, and psychosocial burden associated with pachyonychia congenita, emphasizing the importance of early diagnosis, genetic counseling, and supportive care. RésuméUne fille de 11 ans s’est présentée avec une hyperkératose plantaire douloureuse et une dystrophie unguéale, présentes depuis la petite enfance. L’examen clinique a révélé des plaques hyperkératosiques sur les plantes des pieds, une hypertrophie unguéale en forme de coin, une hyperkératose folliculaire des extrémités et une leucokératose orale. Une histoire maternelle positive suggérait une transmission autosomique dominante avec expressivité variable, compatible avec une pachyonychie congénitale. L’infection fongique a été exclue par un examen au KOH ; le test génétique n’a pas pu être réalisé en raison de contraintes financières. Malgré des traitements antérieurs par kératolytiques et émollients, l’amélioration était minime. Ce cas met en évidence l’apparition précoce, les caractéristiques classiques et le fardeau psychosocial associés à la pachyonychie congénitale, soulignant l’importance du diagnostic précoce, du conseil génétique et de la prise en charge de soutien.

Oral Statin Therapy in KRT16- and KRT17-Associated Palmoplantar Epidermal Differentiation Disorder (Pachyonychia Congenita).
Palmoplantar epidermal differentiation disorder associated with pachyonychia congenita (pEDD-PC) is a rare autosomal dominant skin disorder caused by pathogenic variants in keratin genes, including KRT6A, KRT6B, KRT6C, KRT16, and KRT17. While statins have been reported to alleviate symptoms in KRT6A-pEDD-PC, their efficacy in other subtypes remains unclear. We report six adult patients, including four with KRT17 variants and two with KRT16 variants, who underwent off-label oral statin therapy. Statins were administered for at least 6 months following dose stabilization. Although the treatment was well tolerated in most cases, no significant clinical improvement in plantar calluses or pain was observed. All patients discontinued therapy due to insufficient efficacy. Our findings indicate that oral statin therapy may offer limited benefit in KRT16/KRT17-pEDD-PC and suggest the potential importance of early intervention and genotype-specific therapeutic strategies.
