Variant summary

Our verdict is The variant received 0 classification points (ACGS-UK Somatic Oncogenicity v2025).

The NM_005227.3(EFNA4):c.113+19G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The gene EFNA4 is a known oncogene (CancerMine: 4 oncogene citations). The variant allele was found at a cumulative frequency of 0.00029 (AC=443) in the gnomAD database across 1,528,728 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.000183. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★).

Genes affected

EFNA4 (HGNC:3224): (ephrin A4) This gene encodes a member of the ephrin (EPH) family. The ephrins and EPH-related receptors comprise the largest subfamily of receptor protein-tyrosine kinases and have been implicated in mediating developmental events, especially in the nervous system and in erythropoiesis. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. This gene encodes an EFNA class ephrin that has been implicated in proliferation and metastasis of several types of cancers. [provided by RefSeq, May 2022]
