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]

WDFY3-AS1 (HGNC:40935): (WDFY3 antisense RNA 1)

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 4-84797999-T-A is Pathogenic according to our data. Variant chr4-84797999-T-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 996675.Status of the report is no_assertion_criteria_provided, 0 stars.
