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]

HERC1 Gene-Disease associations (from GenCC):

• macrocephaly, dysmorphic facies, and psychomotor retardation

  Inheritance: AR Classification: DEFINITIVE, STRONG, MODERATE Submitted by: Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)
• megalencephaly-severe kyphoscoliosis-overgrowth syndrome

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
