Genes affected

ATE1 (HGNC:782): (arginyltransferase 1) This gene encodes an arginyltransferase, an enzyme that is involved in posttranslational conjugation of arginine to N-terminal aspartate or glutamate residues. Conjugation of arginine to the N-terminal aspartate or glutamate targets proteins for ubiquitin-dependent degradation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.967

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1109A>G (p.Y370C) alteration is located in exon 9 (coding exon 9) of the ATE1 gene. This alteration results from a A to G substitution at nucleotide position 1109, causing the tyrosine (Y) at amino acid position 370 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
