This variant is present in gnomAD above the CDH1 BS1 threshold of 0.1%, reaching 0.11215% in African/African American individuals in gnomAD v2.1 and 0.16258% in African/African American individuals in gnomAD v4.1, but it remains below the BA1 threshold of 0.2%.

In gnomAD v4.1, this variant is also observed in the homozygous state in 3 individuals, supporting BP2 under the CDH1 specification.

In silico splicing evidence does not support a splice-altering effect, with SpliceAI showing a maximum delta score of 0.01, which is consistent with applying BP7 for this synonymous internal exonic variant and does not support PP3.
