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]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 11, 2023This variant has been observed in individual(s) with clinical features of hereditary spastic paraplegia (PMID: 26437029). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (no rsID available, gnomAD 0.002%). This variant, c.2490_2492del, results in the deletion of 1 amino acid(s) of the HACE1 protein (p.Leu832del), but otherwise preserves the integrity of the reading frame. ClinVar contains an entry for this variant (Variation ID: 221292). 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. -
