Genes affected

HECTD3 (HGNC:26117): (HECT domain E3 ubiquitin protein ligase 3) The protein encoded by this gene transfers ubiquitin from an E2 ubiquitin-conjugating enzyme to targeted substrates, leading to the degradation of those substrates. The encoded protein has been shown to transfer ubiquitin to TRIOBP to facilitate cell cycle progression, and to STX8. [provided by RefSeq, Dec 2012]

The c.2289C>G (p.F763L) alteration is located in exon 18 (coding exon 18) of the HECTD3 gene. This alteration results from a C to G substitution at nucleotide position 2289, causing the phenylalanine (F) at amino acid position 763 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
