Genes affected
EXOG (HGNC:3347): (exo/endonuclease G) This gene encodes an endo/exonuclease with 5'-3' exonuclease activity. The encoded enzyme catalyzes the hydrolysis of ester linkages at the 5' end of a nucleic acid chain. This enzyme is localized to the mitochondria and may play a role in programmed cell death. Alternatively spliced transcript variants have been described. A pseudogene exists on chromosome 18. [provided by RefSeq, Feb 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.664G>A (p.V222M) alteration is located in exon 6 (coding exon 6) of the EXOG gene. This alteration results from a G to A substitution at nucleotide position 664, causing the valine (V) at amino acid position 222 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
