Genes affected

ACE (HGNC:2707): (angiotensin I converting enzyme) This gene encodes an enzyme involved in blood pressure regulation and electrolyte balance. It catalyzes the conversion of angiotensin I into a physiologically active peptide angiotensin II. Angiotensin II is a potent vasopressor and aldosterone-stimulating peptide that controls blood pressure and fluid-electrolyte balance. This angiotensin converting enzyme (ACE) also inactivates the vasodilator protein, bradykinin. Accordingly, the encoded enzyme increases blood pressure and is a drug target of ACE inhibitors, which are often prescribed to reduce blood pressure. This enzyme additionally plays a role in fertility through its ability to cleave and release GPI-anchored membrane proteins in spermatozoa. Many studies have associated the presence or absence of a 287 bp Alu repeat element in this gene with the levels of circulating enzyme. This polymorphism, as well as mutations in this gene, have been implicated in a wide variety of diseases including cardiovascular pathophysiologies, psoriasis, renal disease, stroke, and Alzheimer's disease. Regulation of the homologous ACE2 gene may be involved in progression of disease caused by several human coronaviruses, including SARS-CoV and SARS-CoV-2. Alternative splicing results in multiple transcript variants encoding both somatic (sACE) and male-specific testicular (tACE) isoforms. [provided by RefSeq, Sep 2020]

The R791X pathogenic variant in the ACE gene has been reported previously in the homozygous state in association with renal tubular dysgenesis (Gribouval et al., 2012).This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Functional studies of the R791X mutation (aka R762X using alternate nomenclature) indicate that although it exhibits N-domain enzyme activity, it lacks the C-domain activity and is not properly inserted in the plasma membrane (Michaud et al., 2014). The R791X mutation was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. We interpret R791X as a pathogenic variant. This variant has been seen Paternally inherited. -
