Genes affected

CEACAM19 (HGNC:31951): (CEA cell adhesion molecule 19) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

CEACAM16-AS1 (HGNC:55317): (CEACAM16, CEACAM19 and PVR antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 2 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.55).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.126 is higher than 0.05.
