Genes affected
WIPI1 (HGNC:25471): (WD repeat domain, phosphoinositide interacting 1) This gene encodes a WD40 repeat protein. Members of the WD40 repeat family are key components of many essential biologic functions. They regulate the assembly of multiprotein complexes by presenting a beta-propeller platform for simultaneous and reversible protein-protein interactions. Members of the WIPI subfamily of WD40 repeat proteins have a 7-bladed propeller structure and contain a conserved motif for interaction with phospholipids. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2023The c.1220G>A (p.R407Q) alteration is located in exon 12 (coding exon 12) of the WIPI1 gene. This alteration results from a G to A substitution at nucleotide position 1220, causing the arginine (R) at amino acid position 407 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
