Abstract
Pachyonychia congenita (PC) is a dominantly inherited genetic disorder of cornification. PC stands out among other genodermatoses because despite its rarity, it has been the focus of a very large number of pioneering translational research efforts over the past 2 decades, mostly driven by a patient support organization, the Pachyonychia Congenita Project. These efforts have laid the ground for innovative strategies that may broadly impact approaches to the management of other inherited cutaneous and noncutaneous diseases. This article outlines current avenues of research in PC, expected outcomes, and potential hurdles.

Abstract
Hidradenitis suppurativa (HS) is an autoinflammatory skin disorder of the terminal hair follicle, which can present in sporadic, familial, or syndromic form. A classification has been proposed for the latter, distinguishing cases associated with a known genetic condition, with follicular keratinization disorders or with autoinflammatory diseases. This review focuses on the clinical and genetic features of those entities (ie, pyoderma gangrenosum [PG], acne and HS; PG, acne, pyogenic arthritis and HS; psoriatic arthritis, PG, acne and HS; synovitis, acne, pustulosis, hyperostosis, osteitis; and so forth) for which the collective term HS-related autoinflammatory syndromes is proposed.

Abstract
Genetic aspects have a substantial role in hidradenitis suppurativa (HS) pathogenesis. A positive family history of HS occurs in about one-third of HS cases and is significantly higher in patients with early onset of the disease. Recent twin studies have shown a high heritability in HS, fortifying the importance of genetic factors in disease pathogenesis. Based on existing knowledge on the genomics of HS, the disease can be categorized as familial HS, sporadic, syndromic HS, and "HS plus" associated with other syndromes. In familial HS, autosomal dominant transmission is proposed, and monogenic inheritance is rare. This monogenic trait is related to mutations of γ-secretase component genes and Notch signaling or defects in inflammasome function. With newly discovered gene mutations, such as those related to innate and adaptive immunity, skin microbiome, inflammasome, epidermal homeostasis, and keratinization pathway, we can define HS as a polygenic, multifactorial, autoinflammatory disease. To fully elucidate the genetic aspects of HS, we need extensive, long-term global collaborations.

Abstract
Autosomal recessive congenital ichthyosis (ARCI) refers to a large and genetically heterogenous group of non-syndromic disorders of cornification featuring diffuse scaling. Ichthyosis, leukocyte vacuoles, alopecia, and sclerosing cholangitis (ILVASC) syndrome is a rare autosomal recessive syndromic form of ichthyosis. The disease usually results from premature termination codon-causing pathogenic variants in CLDN1 encoding CLAUDIN-1 (CLDN1). We used whole exome sequencing (WES), Sanger sequencing, 3D protein modeling, Western blotting, and immunofluorescence confocal microscopy to delineate the genetic basis of ichthyosis in two siblings with ichthyosis but no other ectodermal abnormalities. One of the two siblings underwent liver transplantation in early childhood due to biliary atresia. Both patients were found to carry a homozygous missense pathogenic variant, c.242G>A (p.Arg81His), in CLDN1. The variant resulted in decreased CLDN1 expression in patient skin. 3D protein modeling predicted that p.Arg81His induces deleterious conformational changes. Accordingly, HaCaT cells transfected with a construct expressing the mutant CLDN1 cDNA featured decreased levels and mislocation of CLDN1 as compared with cells expressing the wildtype cDNA. In conclusion, we describe the first pathogenic missense variant in CLDN1 shown to result in ARCI.
