In OMIM WIPF1 is provisionally associated with Wiskott-Aldrich syndrome 2. OMIM reports only one case of a patient with Wiskott-Aldrich syndrome 2 and a variant identified in WIPF1: Lanzi et al. (2012)(PMID: 22231303) identified a homozygous ser434-to-ter (S434X; 602357.0001) mutation in the WIPF1 gene of a Moroccan infant. The patient's parents, who were consanguineous, were heterozygous for the mutation. WIPF1 encodes the Wiskott-Aldrich Syndrome Interacting Protein (WIP) and interacts with WASP ( Ramesh et al. (1997)(PMID: 9405671). Variants in WASP are reported to cause Wiskott-Aldrich Syndrome (OMIM: 301000). Wip -/- mice show defects in aspects of their immune responses (Anton et al. (2002)(PMID: 11869681), Kettner et al. (2004)(PMID:14757742.

Two unrelated cases reported in the literature. The first report was an 11-day-old Moroccan girl with Wiskott-Aldrich syndrome-2, this second described was from a large consanguineous family with 4 affecteds, a further 8 cases did not have the chance for full evaluation due to early infantile death, but it as assumed they had the same disease-based clinical presentation of recurrent infections, bloody diarrhea, and thrombocytopenia.

from Al-Mousa H et al. (2017) PMID: 27742395 identified a second family with WIP deficiency. Two variants have now been described in the literature, homozygous ser434-to-ter (S434X; 602357.0001) and a homozygous nonsense mutation (c.709 C>T) (p.Q237X) in the WIPF1 gene. Wiskott-Aldrich syndrome (WAS) is an X-linked primary immunodeficiency disease characterized by immune deficiency, thrombocytopenia, and eczema. A novel primary immunodeficiency had previously been reported in a single patient with a nonsense mutation in WIPF1 (PMID:22231303 ), the gene that encodes WIP, producing a protein that lacks a WASP-binding site with defective WASP expression. This single patient was reported to have been successfully transplanted using unrelated umbilical cord stem cell. Details of stem cell transplantation and immune reconstitution were not provided PMID: 22231303. In Al-Mousa H et al. (2017) PMID: 27742395 reported 4 patients with WIP deficiency who underwent stem cell transplantation along with their detailed clinical features, stem cell transplantation, and immune reconstitution. All 4 patients presented with a history of recurrent infections and thrombocytopenia. They belonged to a large sibship of 12 in a highly consanguineous family originating from the Southern province of Saudi Arabia.

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s)
GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.
