Enterokinase deficiency with novel TMPRSS15 gene mutation masquerading as acrodermatitis enteropathica.

Abstract excerpt

Enterokinase deficiency (EKD) is a rare autosomal recessive inherited disorder caused by loss-of-function mutations of the transmembrane protease serine 15 (TMPRSS15) gene. To date, only 12 cases of EKD have been described in the literature and skin involvement has seldom been described. We identified a novel homozygous nonsense mutation in the TMPRSS15 gene (c.1216C>T, p.R406*) in a female infant, who manifested...
