Genes affected

WDFY3 (HGNC:20751): (WD repeat and FYVE domain containing 3) This gene encodes a phosphatidylinositol 3-phosphate-binding protein that functions as a master conductor for aggregate clearance by autophagy. This protein shuttles from the nuclear membrane to colocalize with aggregated proteins, where it complexes with other autophagic components to achieve macroautophagy-mediated clearance of these aggregated proteins. However, it is not necessary for starvation-induced macroautophagy. [provided by RefSeq, May 2010]

The c.10280T>C (p.V3427A) alteration is located in exon 67 (coding exon 64) of the WDFY3 gene. This alteration results from a T to C substitution at nucleotide position 10280, causing the valine (V) at amino acid position 3427 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
