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 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 07, 2024The c.1171G>A (p.V391M) alteration is located in exon 8 (coding exon 8) of the ECE2 gene. This alteration results from a G to A substitution at nucleotide position 1171, causing the valine (V) at amino acid position 391 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
