پروتئین شماره ۴ دومین تکرارهای WD، واکنشدهنده با فسفواینوزیتید (انگلیسی: WD repeat domain phosphoinositide-interacting protein 4) که به اختصار WDR45 یا WIPI-4 نامیده میشود، یک پروتئین است که در انسان توسط ژن «WDR45» کُدگذاری میشود.[۵][۶]
جهشهای کارکردزُدا (Loss of function mutation) و جدید در این ژن، در ۲۰ بیمار مبتلا به «تخریب عصبی با تجمع آهن در مغز» یافت شدهاست[۷] که سبب بروز نوع خاصی از آن میگردد که وابسته به کروموزوم ایکس و غالب است و امروزه به آن «تخریب عصبی مرتبط با پروتئین بتا-پروپلر» (BPAN) میگویند.[۷]

"Exome Sequencing Reveals De Novo WDR45 Mutations Causing a Phenotypically Distinct, X-Linked Dominant Form of NBIA". Am J Hum Genet. 91 (6): 1144–9. doi:10.1016/j.ajhg.2012.10.019. PMID23176820. This clinically recognizable disorder is among the more common forms of NBIA, and we suggest that it be named accordingly as beta-propeller protein-associated neurodegeneration.
