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

Verdict is Benign. Variant got -9 ACMG points.

• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), HERC2. . Gene score misZ 4.4237 (greater than the threshold 3.09). Trascript score misZ 7.8111 (greater than threshold 3.09). GenCC has associacion of gene with developmental delay with autism spectrum disorder and gait instability.
• BP4: Computational evidence support a benign effect (MetaRNN=0.014858425).
• BP6: Variant 15-28113673-T-C is Benign according to our data. Variant chr15-28113673-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 2498604.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr15-28113673-T-C is described in Lovd as [Likely_benign].
• BS2: High Homozygotes in GnomAd4 at 2 AD,AR gene
