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 -13 ACMG points.

PP2

Missense variant in the ERBB2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 24 curated pathogenic missense variants (we use a threshold of 10). The gene has 24 curated benign missense variants. Gene score misZ: 3.2497 (above the threshold of 3.09). Trascript score misZ: 4.234 (above the threshold of 3.09). GenCC associations: The gene is linked to visceral neuropathy, familial, 2, autosomal recessive, lung cancer, Hirschsprung disease, glioma susceptibility 1.

BP4

Computational evidence support a benign effect (MetaRNN=0.0039918125).

BP6

Variant 17-39727758-G-A is Benign according to our data. Variant chr17-39727758-G-A is described in ClinVar as [Benign]. Clinvar id is 134085.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00217 (330/152302) while in subpopulation AFR AF= 0.0077 (320/41564). AF 95% confidence interval is 0.007. There are 2 homozygotes in gnomad4. There are 157 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
