In a mother and her 2 children with AEI, Suga et al. (1998) screened the KRT1, KRT2, and KRT10 genes and identified heterozygosity for a missense mutation in the KRT10 gene (I107T; 148080.0028). The mutation was not found in unaffected family members or in 50 controls. Given the similarities between various ichthyoses, a diagnosis of epidermolytic ichthyosis can be made using clinical, histopathological, and laboratory findings. The diagnosis can be confirmed with genetic testing [1–3]. Polkoff KM et al.

What is the outcome for epidermolytic ichthyosis?

Renz et al. (2019) noted that the genodermatosis IWC is caused by dominant-negative variants that result in aberrant KRT10 proteins that localize to the nucleus rather than the cytoplasm. The mislocalization is associated with a C terminus that is altered from a polyglycine tail to either a polyarginine or polyalanine tail. Renz et al. (2019) demonstrated that only K10 with an arginine-rich C terminus (K10arg) translocates to the nucleus, whereas wildtype K10, K10ala, and truncated K10 remain in the cytoplasm. The authors also showed that the presence of K10arg enables cotranslocation of non-K10arg proteins into the nucleus. They concluded that arginine-rich K10 tails are responsible for the pathogenic nuclear localization of K10 in patients with IWC. To date, the nondecoy functions of DcR3 responsible for some cellular functions and therapeutic potentials have been documented. These include driving dendritic cell and macrophage polarization toward Th2 phenotypes and M2-like phenotypes, respectively 32, 34. Despite accumulating lines of evidence indicating the effector function of extracellular DcR3 3, only a limited understanding of the mechanism of action has been obtained. In this respect, extracellular DcR3 can interact with heparin sulfate proteoglycans (HSPGs), such as syndecans and CD44v3, in myeloid cells 4, induce M2 macrophage polarization via epigenetic regulation 33, 34, and induce monocyte adhesion via activation of FAK 31. Despite these findings, the possible intracellular action of DcR3 is totally unknown. In this study, we identified a novel intracellular target of DcR3. We demonstrated the interactions of intracellular DcR3 with PKCα and PKCδ and found that these interactions contribute to constitutive PKC activation. Because resting PKC activity can be controlled by EGFR 43 and regulate keratinocyte differentiation 44, 45, we speculate that DcR3-mediated regulation of keratinocyte differentiation might involve PKC activity. a b "Entrez Gene: KRT10 keratin 10 (epidermolytic hyperkeratosis; keratosis palmaris et plantaris)".

In a 28-year-old Caucasian man (IWC100) with IWC, Lim et al. (2016) sequenced the KRT10 gene and identified a de novo heterozygous 1-bp deletion ( 148080.0024), causing a frameshift predicted to replace the endogenous glycine-rich tail domain of keratin-10 with an alanine-rich motif that extends the C terminus by 19 additional amino acids. Laser capture microdissection of patient white spots revealed that each revertant spot harbored copy-neutral loss of heterozygosity in the proximal q arm of chromosome 17 extending to the telomere, consistent with reversion via mitotic recombination. However, Renz et al. (2019) analyzed the 1-bp deletion in patient IWC100 and demonstrated that the variant leads to several alternative splicing products, the majority of which result in an arginine-rich C terminus.
