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]

Pathogenic:1Uncertain:1

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Mar 11, 2023	This 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. -
