In OMIM PSENEN is associated with Acne inversa, familial, 2, with or without Dowling-Degos disease. Several studies report patients with this disorder and variants in the PSENEN gene (Wang et al. (2010) (PMID: 20929727]), Pink et al. (2011)(PMID: 21412258), Zhou et al. (2016) (PMID: 27900998), Ralser et al. (2017) (PMID: 28287404), Li et al. (2017) (PMID: 28601418)) - 13 families in total, 7 different variants reported in OMIM. OMIM reports that Li et al. (2017) observed intrafamilial variability in severity of lesions, which they suggested might be due to reduced penetrance involving different genetic and environmental factors. Wollina et al. (2013)(PMID: 23439959) review the pathogenesis and treatment of Acne inversa (Hidradenitis suppurativa) and describe the possible role of the immune system in this disorder. PSENEN is part of the gamma-Secretase complex which is involved in the regulation of the canonical Notch signalling pathway. Melnik and Plewig (2013)(PMID: 23020871) describe a model for impaired Notch signalling affecting the immune functions of T helper cells (Figure 2). However, impairment of Notch signalling may also contribute to other clinical manifestations of the disorder such as inhibition of the hair growth cycle, conversion of hair follicles intocysts, and inhibition of sebaceous gland differentiation (Pavlovsky et al. (2017)(PMID: 28922471).
