Genes affected

EXD2 (HGNC:20217): (exonuclease 3'-5' domain containing 2) Enables 3'-5' exonuclease activity; metal ion binding activity; and protein homodimerization activity. Involved in nucleic acid metabolic process. Located in intermediate filament cytoskeleton; mitochondrial outer membrane; and site of DNA damage. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Sep 01, 2024

The c.35C>T (p.T12I) alteration is located in exon 3 (coding exon 1) of the EXD2 gene. This alteration results from a C to T substitution at nucleotide position 35, causing the threonine (T) at amino acid position 12 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
