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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), HERC1. . Gene score misZ 4.9558 (greater than the threshold 3.09). Trascript score misZ 5.2706 (greater than threshold 3.09). GenCC has associacion of gene with macrocephaly, dysmorphic facies, and psychomotor retardation, megalencephaly-severe kyphoscoliosis-overgrowth syndrome.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.909

The c.14312T>A (p.L4771H) alteration is located in exon 77 (coding exon 76) of the HERC1 gene. This alteration results from a T to A substitution at nucleotide position 14312, causing the leucine (L) at amino acid position 4771 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
