WD repeat domain phosphoinositide-interacting protein 4 (WIPI-4) is a protein that in humans is encoded by the WDR45 gene.^[3][4] Mutations in this gene cause NBIA.^[5]

Function

WIPI-4 is a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. This gene has a pseudogene at chromosome 4q31.3. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene, but the biological validity and full-length nature of some variants have not been determined.^[4]

Role in Disease

De novo loss of function mutations in WDR45 were identified by exome sequencing in 20 patients with Neurodegeneration with brain iron accumulation (NBIA).^[5]
