Identification of a novel C16orf57 mutation in Athabaskan patients with Poikiloderma with Neutropenia.
Poikiloderma with Neutropenia (PN), Clericuzio-Type (OMIM #604173) is characterized by poikiloderma, chronic neutropenia, recurrent sinopulmonary infections, bronchiectasis, and nail dystrophy. First described by Clericuzio in 1991 in 14 patients of Navajo descent, it has since also been described in non-Navajo patients. C16orf57 has recently been identified as a causative gene in PN. The purpo...
متن کاملTargeted next-generation sequencing appoints c16orf57 as clericuzio-type poikiloderma with neutropenia gene.
Next-generation sequencing is a straightforward tool for the identification of disease genes in extended genomic regions. Autozygosity mapping was performed on a five-generation inbred Italian family with three siblings affected with Clericuzio-type poikiloderma with neutropenia (PN [MIM %604173]), a rare autosomal-recessive genodermatosis characterised by poikiloderma, pachyonychia, and chroni...
متن کاملA zebrafish model of Poikiloderma with Neutropenia recapitulates the human syndrome hallmarks and traces back neutropenia to the myeloid progenitor
Poikiloderma with Neutropenia (PN) is an autosomal recessive genodermatosis characterized by early-onset poikiloderma, pachyonychia, hyperkeratosis, bone anomalies and neutropenia, predisposing to myelodysplasia. The causative C16orf57/USB1 gene encodes a conserved phosphodiesterase that regulates the stability of spliceosomal U6-RNA. The involvement of USB1 in splicing has not yet allowed to u...
متن کاملAberrant 3' oligoadenylation of spliceosomal U6 small nuclear RNA in poikiloderma with neutropenia.
The recessive disorder poikiloderma with neutropenia (PN) is caused by mutations in the C16orf57 gene that encodes the highly conserved USB1 protein. Here, we present the 1.1 Å resolution crystal structure of human USB1, defining it as a member of the LigT-like superfamily of 2H phosphoesterases. We show that human USB1 is a distributive 3'-5' exoribonuclease that posttranscriptionally removes ...
متن کاملAbsence of RECQL4 mutations in poikiloderma with neutropenia in Navajo and non-Navajo patients.
Poikiloderma with neutropenia (PN), previously referred to as Navajo poikiloderma (MIM #604173) is a rare, autosomal recessive disorder first described by Clericuzio et al. [1991] in the Navajo American Indian population [Erickson, 1999]. It is characterized by a distinctive poikilodermatous rash, noncyclical neutropenia, small stature, pachyonychia, and pulmonary disease (reactive airway disea...
