Genes affected

HERC1 (HGNC:4867): (HECT and RLD domain containing E3 ubiquitin protein ligase family member 1) This gen encodes a member of the HERC protein family. This protein stimulates guanine nucleotide exchange on ARF1 and Rab proteins. This protein may be involved in membrane transport processes. [provided by RefSeq, Mar 2012]

ACMG classification

Verdict is Benign. Variant got -19 ACMG points.

• PP2: Missense variant where missense usually causes diseases, HERC1
• BP4: Computational evidence support a benign effect (MetaRNN=8.076119E-5).
• BP6: Variant 15-63678257-T-C is Benign according to our data. Variant chr15-63678257-T-C is described in ClinVar as [Benign]. Clinvar id is 1260045.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.538 is higher than 0.05.
