Genes affected

ESAM (HGNC:17474): (endothelial cell adhesion molecule) Enables cell-cell adhesion mediator activity. Involved in several processes, including bicellular tight junction assembly; cell-cell adhesion; and regulation of actin cytoskeleton organization. Located in cell-cell junction and plasma membrane. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

ESAM Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with intracranial hemorrhage, seizures, and spasticity

  Inheritance: AR Classification: DEFINITIVE, STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), G2P, Ambry Genetics

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3960103).
