Genes affected
AOPEP (HGNC:1361): (aminopeptidase O (putative)) This gene encodes a member of the M1 zinc aminopeptidase family. The encoded protein is a zinc-dependent metallopeptidase that catalyzes the removal of an amino acid from the amino terminus of a protein or peptide. This protein may play a role in the generation of angiotensin IV. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2010]

AOPEP-related disorder Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesJul 18, 2023The AOPEP c.1215delT variant is predicted to result in a frameshift and premature protein termination (p.Val406Cysfs*14). This variant was reported, along with another pathogenic variant, in an individual with dystonia (Zech et al. 2022. PubMed ID: 34596301). This variant is reported in 0.011% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/9-97563134-CT-C). Frameshift variants in AOPEP are expected to be pathogenic. This variant is interpreted as likely pathogenic. -
