Variant summary

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

The NM_001384479.1(AGT):c.803C>A (p.Ala268Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene AGT is a tumor suppressor gene (CancerMine: 1 TSG, 1 oncogene, 1 driver citations). The gene AGT is a known oncogene (CancerMine: 1 TSG, 1 oncogene, 1 driver citations). The gene AGT is a cancer driver gene (CancerMine: 1 TSG, 1 oncogene, 1 driver citations). The variant allele was found at a cumulative frequency of 0.000000684 (AC=1) in the gnomAD database across 1,461,848 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.000000899. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★).

Genes affected

AGT (HGNC:333): (angiotensinogen) The protein encoded by this gene, pre-angiotensinogen or angiotensinogen precursor, is expressed in the liver and is cleaved by the enzyme renin in response to lowered blood pressure. The resulting product, angiotensin I, is then cleaved by angiotensin converting enzyme (ACE) to generate the physiologically active enzyme angiotensin II. The protein is involved in maintaining blood pressure, body fluid and electrolyte homeostasis, and in the pathogenesis of essential hypertension and preeclampsia. Mutations in this gene are associated with susceptibility to essential hypertension, and can cause renal tubular dysgenesis, a severe disorder of renal tubular development. Defects in this gene have also been associated with non-familial structural atrial fibrillation, and inflammatory bowel disease. [provided by RefSeq, Nov 2019]
