Evidence submitted by expert panel

CDH1 VCEP

The c.105G>C (NM_004360.5) variant in CDH1 is a missense variant predicted to predicted to cause substitution of Glu by Asp at amino acid 35 (p.Glu35Asp). This variant has been observed in more than 3 heterozygous individuals without GC, DGC, SRC tumours or LBC and whose families do not suggest HDGC (BS2_Supporting; Ambry, GeneDx, Invitae). This variant is absent from gnomAD 2.1.1 (PM2_Supporting). In summary, this variant meets the criteria to be classified as uncertain significance for DGLBCS based on the ACMG/AMP criteria applied, as specified by the ClinGen CDH1 VCEP (CDH1 VCEP specifications version 3.1): PM2_Supporting, BS2_Supporting.

PM2_Supporting

This variant is absent from gnomAD 2.1.1 (PM2_Supporting).

BS2_Supporting

This variant has been observed in six individuals without GC, DGC, SRC tumours or LBC and whose families do not suggest HDGC (BS2_Supporting; Ambry, GeneDx, Invitae). Note that this includes one individual with IDC with lobular features and one unaffected individual with a family history of gastric cancer.

PS1

No other pathogenic missense variants have been reported.

PS2

To our knowledge, this variant has not been reported as de novo.

PS4

This variant has been observed in five individuals without DGC, LBC, SRC tumours and whose families do not suggest HDGC (Ambry, GeneDx, Invitae). Note that this includes one individual with IDC with lobular features (Invitae).

PS3

Functional studies have not been reported for this variant.

PP4

PP4 does not apply to CDH1.

PP1

Not available.

PP3

Multiple computational tools do not suggest that this variant impacts splicing.

PP2

PP2 does not apply to CDH1.

PM6

To our knowledge, this variant has not been reported as de novo.

PM5

PM5 does not apply to CDH1.

PM3

PM3 does not apply to CDH1.

PM1

PM1 does not apply to CDH1.

PM4

PM4 does not apply to this variant.

PVS1

BA1

This variant is absent from gnomAD.

BS4

Not available.

BS3

Functional studies have not been reported for this variant.

BS1

This variant is absent from gnomAD.

BP5

To our knowledge, this variant has not been reported in a case with an alternate molecular basis for disease.

BP7

BP7 does not apply to this variant.

BP2

To our knowledge, this variant has not been reported in cis or trans with a known pathogenic variant.

BP3

BP3 does not apply to CDH1.

BP4

Multiple computational tools do not suggest that this variant impacts splicing.

BP1

BP1 does not apply to CDH1.
