• chr12-15623289-TA-T

Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP6_Very_Strong BS1

The NM_004447.6(EPS8):​c.2226-3del variant causes a splice region, splice polypyrimidine tract, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00336 in 136,300 control chromosomes in the GnomAD database, with no homozygous occurrence. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Likely benign (★★).

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP6: Variant 12-15623289-TA-T is Benign according to our data. Variant chr12-15623289-TA-T is described in ClinVar as [Likely_benign]. Clinvar id is 666690.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00336 (458/136300) while in subpopulation NFE AF= 0.0034 (210/61822). AF 95% confidence interval is 0.00302. There are 0 homozygotes in gnomad4. There are 269 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
