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 GeneticsJul 26, 2021The c.103G>T (p.A35S) alteration is located in exon 1 (coding exon 1) of the EXOG gene. This alteration results from a G to T substitution at nucleotide position 103, causing the alanine (A) at amino acid position 35 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
