Genes affected

ENDOG (HGNC:3346): (endonuclease G) The protein encoded by this gene is a nuclear encoded endonuclease that is localized in the mitochondrion. The encoded protein is widely distributed among animals and cleaves DNA at GC tracts. This protein is capable of generating the RNA primers required by DNA polymerase gamma to initiate replication of mitochondrial DNA. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3325822).

Ambry Genetics

Sep 22, 2023

The c.187G>A (p.E63K) alteration is located in exon 1 (coding exon 1) of the ENDOG gene. This alteration results from a G to A substitution at nucleotide position 187, causing the glutamic acid (E) at amino acid position 63 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
