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]

Computational evidence support a benign effect (BayesDel_noAF=-0.78).
BP6
Variant 1-16148520-G-A is Benign according to our data. Variant chr1-16148520-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 468225.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=-6.03 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000438 (64/1461200) while in subpopulation AMR AF = 0.000246 (11/44702). AF 95% confidence interval is 0.000137. There are 0 homozygotes in GnomAdExome4. There are 27 alleles in the male GnomAdExome4 subpopulation. Median coverage is 47. This position passed quality control check.
