Genes affected

EEF1AKMT4 (HGNC:53611): (EEF1A lysine methyltransferase 4) This gene encodes a member of the lysine-specific methyltransferase (KMT) family. The encoded enzyme catalyzes the methylation of lysine-36 of the eukaryotic translation elongation factor 1 alpha. Methylation by this enzyme may affect endoplasmic reticulum-related processes. [provided by RefSeq, Jul 2017]

EEF1AKMT4 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]

Ambry Genetics

Aug 01, 2024

The c.397C>G (p.L133V) alteration is located in exon 2 (coding exon 2) of the ECE2 gene. This alteration results from a C to G substitution at nucleotide position 397, causing the leucine (L) at amino acid position 133 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
