Genes affected

AMIGO2 (HGNC:24073): (adhesion molecule with Ig like domain 2) Predicted to be involved in several processes, including heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; homophilic cell adhesion via plasma membrane adhesion molecules; and negative regulation of programmed cell death. Predicted to act upstream of or within positive regulation of synapse assembly. Predicted to be located in nucleus and plasma membrane. Predicted to be integral component of membrane. Biomarker of gastric adenocarcinoma. [provided by Alliance of Genome Resources, Apr 2022]

PCED1B (HGNC:28255): (PC-esterase domain containing 1B) This gene encodes a protein that belongs to the GDSL/SGNH-like acyl-esterase family. Members of this family are hydrolases thought to function in modification of biopolymers on the cell surface. Alternate splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2013]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.04276374).
