Variant summary
Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BS2BP2_Strong
This summary comes from the ClinGen Evidence Repository: The c.671G>A (p.Arg224His) missense variant has a frequency of 0. 0.00003189 (8 of 250,850) in the gnomAD v2.1.1 cohort, with a maximum non-founder allele frequency of 0.00006179 (7 of 113,278) in the African subpopulation (http://gnomad.broadinstitute.org). This variant has been observed in >50 individuals w/o DCG, SRC tumors, or LBC & whose families do not suggest HDGC (BS2; SCV000637843.5, SCV000278911.9). This variant was observed in the homozygous state in an individual without DGC, SRC tumors or LBC and whose family does not suggest HDGC (BP2_Strong, internal laboratory contributor). In summary, the clinical significance of this variant is classified as benign based the ACMG/AMP criteria applied, as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): BS2, BP2_Strong.

Hereditary diffuse gastric adenocarcinoma Uncertain:2Benign:5
BP2_Strong; BS2 (PMID: 30311375)
This variant is classified as a variant of uncertain significance as there is insufficient evidence to determine its impact on protein function and/or cancer risk.
This submission and the accompanying classification are no longer maintained by the submitter. For more information on current observations and classification, please contact variantquestions@myriad.com.
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
Hereditary cancer-predisposing syndrome Benign:3
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
not provided Uncertain:2
In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with breast, ovarian, or prostate cancer (Lu 2015, Hauke 2018, Huang 2018); This variant is associated with the following publications: (PMID: 22703879, 25583476, 26689913, 27720647, 26486520, 26517685, 28135145, 25503501, 29522266, 15235021, 22850631, 29625052)
