Genes affected

HACE1 (HGNC:21033): (HECT domain and ankyrin repeat containing E3 ubiquitin protein ligase 1) This gene encodes a HECT domain and ankyrin repeat-containing ubiquitin ligase. The encoded protein is involved in specific tagging of target proteins, leading to their subcellular localization or proteasomal degradation. The protein is a potential tumor suppressor and is involved in the pathophysiology of several tumors, including Wilm's tumor. [provided by RefSeq, Mar 2016]

ACMG classification

Verdict is Pathogenic. Variant got 12 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 6-104784998-G-A is Pathogenic according to our data. Variant chr6-104784998-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 548455.Status of the report is criteria_provided_single_submitter, 1 stars.
