Inflammatory skin and bowel disease, neonatal, 2

Summary

Neonatal nephrocutaneous inflammatory syndrome (NNCIS) is an autosomal recessive disorder characterized by intrauterine growth retardation and premature birth, fragile infection-prone skin, and nephromegaly with tubular dysfunction. Some patients have chronic diarrhea, and necrotizing enterocolitis with intestinal perforation has been observed. Other features include facial dysmorphisms and cardiac anomalies. Most patients require ventilatory and circulatory support at birth, exhibit failure to thrive, experience recurrent infections with sepsis as a common complication, and die within 6 months (Mazurova et al., 2020; Labbouz et al., 2023). Reviews Takeichi and Akiyama (2021) reviewed published reports of patients with mutation in the EGFR gene, whose features included intrauterine growth restriction; thin, translucent, and fragile skin (14 of 15 cases); skin desquamation (10 of 17 cases); ichthyosis (9 of 17 cases); recurrent skin infections and sepsis (9 of 12 cases); nephromegaly (10 of 16 cases); and congenital heart defects (7 of 17 cases). Other observed features included erythroderma, tubulopathy, necrotizing enterocolitis/intestinal perforation, cryptorchidism, hyperimmunoglobulin E, and dentinogenesis imperfecta. Almost all children died within 2.5 years after birth. The authors suggested that EGFR-associated systemic inflammatory diseases should be considered a part of the clinical spectrum of 'autoinflammatory keratinization diseases' (AiKDs). [from OMIM]
