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]

ECE2 links:

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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.886T>C (p.Y296H) alteration is located in exon 5 (coding exon 5) of the ECE2 gene. This alteration results from a T to C substitution at nucleotide position 886, causing the tyrosine (Y) at amino acid position 296 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
