Genes affected
ERBB2 (HGNC:3430): (erb-b2 receptor tyrosine kinase 2) This gene encodes a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele, Ile654/Ile655, shown here. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ERBB2. . Gene score misZ 3.2497 (greater than the threshold 3.09). Trascript score misZ 4.234 (greater than threshold 3.09). GenCC has associacion of gene with visceral neuropathy, familial, 2, autosomal recessive, lung cancer, Hirschsprung disease, glioma susceptibility 1.
BP4
Computational evidence support a benign effect (MetaRNN=0.008421838).
BP6
Variant 17-39727923-C-A is Benign according to our data. Variant chr17-39727923-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 134084.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00559 (851/152354) while in subpopulation NFE AF= 0.00783 (533/68032). AF 95% confidence interval is 0.00728. There are 6 homozygotes in gnomad4. There are 437 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 6 AR gene
