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 Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.2605C>A (p.L869I) alteration is located in exon 23 (coding exon 23) of the HACE1 gene. This alteration results from a C to A substitution at nucleotide position 2605, causing the leucine (L) at amino acid position 869 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
