title: Clericuzio-type Poikiloderma with Neutropenia Syndrome in a Turkish Family: a Three Report of Siblings with Mutation in the C16orf57 gene.
abstract: Clericuzio-type poikiloderma with neutropenia (PN) is characterized by poikiloderma, non-cyclic neutropenia, recurrent sinopulmonary infections, pachyonychia, and palmo-plantar hyperkeratosis. Mutations in the C16orf57 gene, which is located on chromosome 16q13, have been identified as the cause of PN. PN was first described by Clericuzio in Navajo Indians. Herein, we reported the clinical presentations and laboratory investigations of PN in three siblings from Turkey. The older siblings presented with typical cutaneous poikiloderma, plantar keratoderma, pachyonychia of toenails, and recurrent upper respiratory infections. As the most affected patient, in addition to classic manifestations, the youngest sibling had recurrent pneumonia, hepatosplenomegaly, dental caries, failure to thrive, and hand malformation. Genetic study revealed a homozygous mutation (c.531delA) in the C16orf57 gene in siblings. With the presented study, we aimed to draw attention to PN which can be a predisposing factor to malignancies.
