Genes affected
ECE2 (HGNC:13275): (endothelin converting enzyme 2) Enables metalloendopeptidase activity. Involved in peptide hormone processing. Located in cytoplasmic vesicle membrane. [provided by Alliance of Genome Resources, Apr 2022]
EEF1AKMT4-ECE2 (HGNC:53615): (EEF1AKMT4-ECE2 readthrough) This gene represents naturally occurring readthrough transcription between adjacent genes eukaryotic translation elongation factor 1 alpha lysine methyltransferase 4 (GeneID: 110599564) and endothelin converting enzyme 2 (GeneID:9718). The readthrough transcript representing this gene encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Jul 2017]

Submissions by phenotype

not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2022This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
