X-24057417-A-G

Variant summary

Our verdict is Benign. Variant got -10 ACMG points: 2P and 12B. PM2 BP4_Strong BP6_Very_Strong

The NM_001415.4(EIF2S3):c.134-4A>G variant causes a splice region, splice polypyrimidine tract, intron change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Likely benign (★★).

Genes affected

EIF2S3 (HGNC:3267): (eukaryotic translation initiation factor 2 subunit gamma) The protein encoded by this gene is the largest subunit of a heterotrimeric GTP-binding protein involved in the recruitment of methionyl-tRNA(i) to the 40 S ribosomal subunit. [provided by RefSeq, Jan 2010]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BP6: Variant X-24057417-A-G is Benign according to our data. Variant chrX-24057417-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 512433.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
