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]

This sequence change creates a premature translational stop signal (p.Gly852Trpfs*33) in the HACE1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 58 amino acid(s) of the HACE1 protein. This variant is present in population databases (rs745394044, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with HACE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1331677). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
