Genes affected

EPS8 (HGNC:3420): (EGFR pathway substrate 8, signaling adaptor) This gene encodes a member of the EPS8 family. This protein contains one PH domain and one SH3 domain. It functions as part of the EGFR pathway, though its exact role has not been determined. Highly similar proteins in other organisms are involved in the transduction of signals from Ras to Rac and growth factor-mediated actin remodeling. Alternate transcriptional splice variants of this gene have been observed but have not been thoroughly characterized. [provided by RefSeq, Jul 2008]

EPS8 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000225 (33/146964) while in subpopulation AFR AF= 0.000827 (33/39894). AF 95% confidence interval is 0.000605. There are 1 homozygotes in gnomad4. There are 15 alleles in male gnomad4 subpopulation. Median coverage is 27. This position pass quality control queck.
