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 Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), WDFY3. . Gene score misZ 5.8174 (greater than the threshold 3.09). Trascript score misZ 7.6797 (greater than threshold 3.09). GenCC has associacion of gene with syndromic intellectual disability, complex neurodevelopmental disorder, autism spectrum disorder.
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
