Genes affected

HERC2 (HGNC:4868): (HECT and RLD domain containing E3 ubiquitin protein ligase 2) This gene belongs to the HERC gene family that encodes a group of unusually large proteins, which contain multiple structural domains. All members have at least 1 copy of an N-terminal region showing homology to the cell cycle regulator RCC1 and a C-terminal HECT (homologous to E6-AP C terminus) domain found in a number of E3 ubiquitin protein ligases. Genetic variations in this gene are associated with skin/hair/eye pigmentation variability. Multiple pseudogenes of this gene are located on chromosomes 15 and 16. [provided by RefSeq, Mar 2012]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

PVS1

Stoplost variant. No alternative stopcodon identified downstream, so we assume a Nonstop Mediated Decay. LoF is a known mechanism of disease.

Variant summary: HERC2 c.14497_*2del11 (p.Gly4833TrpfsX8) causes a frameshift which results in an extension of the protein. The variant allele was found at a frequency of 4e-05 in 251362 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in HERC2 causing Intellectual Developmental Disorder, Autosomal Recessive 38, allowing no conclusion about variant significance. To our knowledge, no occurrence of c.14497_*2del11 in individuals affected with Intellectual Developmental Disorder, Autosomal Recessive 38 and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as uncertain significance. -
