Genetic Variant ENSG00000297913:n.108-16681A>G (chr1-159709846-A-G) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is The variant received 2 classification points (ACGS-UK Somatic Oncogenicity v2025). O3_Moderate

The ENST00000751816.1(ENSG00000297913):n.108-16681A>G variant causes a intron change involving the alteration of a non-conserved nucleotide. Note: ENST00000751816.1 is not a MANE Select or MANE Plus Clinical transcript for ENSG00000297913; the reported annotation may differ from that of the MANE-designated reference transcript for this gene. The variant has a gnomAD grpmax filtering allele frequency (95% CI) of 0.0000147, indicating it is observed in the general population. Note: a gnomAD entry for this variant shows a statistical allele-bias signature, consistent with mosaic/somatic contamination (e.g. age-related clonal hematopoiesis) rather than true inherited population frequency — this frequency should not be read as evidence of a common, benign germline variant. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.
