Genes affected

EPHA2 (HGNC:3386): (EPH receptor A2) This gene belongs to the ephrin receptor subfamily of the protein-tyrosine kinase family. EPH and EPH-related receptors have been implicated in mediating developmental events, particularly in the nervous system. Receptors in the EPH subfamily typically have a single kinase domain and an extracellular region containing a Cys-rich domain and 2 fibronectin type III repeats. The ephrin receptors are divided into 2 groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. This gene encodes a protein that binds ephrin-A ligands. Mutations in this gene are the cause of certain genetically-related cataract disorders.[provided by RefSeq, May 2010]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BS1: Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.00000645 (7/1084960) while in subpopulation EAS AF= 0.00057 (7/12270). AF 95% confidence interval is 0.000267. There are 0 homozygotes in gnomad4_exome. There are 5 alleles in male gnomad4_exome subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAdExome4 at 7 AD gene.
