Genes affected
AGTR1 (HGNC:336): (angiotensin II receptor type 1) Angiotensin II is a potent vasopressor hormone and a primary regulator of aldosterone secretion. It is an important effector controlling blood pressure and volume in the cardiovascular system. It acts through at least two types of receptors. This gene encodes the type 1 receptor which is thought to mediate the major cardiovascular effects of angiotensin II. This gene may play a role in the generation of reperfusion arrhythmias following restoration of blood flow to ischemic or infarcted myocardium. It was previously thought that a related gene, denoted as AGTR1B, existed; however, it is now believed that there is only one type 1 receptor gene in humans. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Aug 2020]

Renal tubular dysgenesis Pathogenic:2
Likely pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMar 05, 2021The p.Ile73HisfsX37 variant in AGTR1 has been identified in one individual with Renal tubular dysgenesis who has a second AGTR1 variant and in an individual with Brugada syndrome (Gribouval 2005 PMID: 16116425, Resta 2015 PMID: 26220970). This variant has also been identified in 0.001% (1/113662) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at position 73 and leads to a premature termination codon 37 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely pathogenic for autosomal recessive renal tubular dysgenesis.
