Genes affected

APOBEC2 (HGNC:605): (apolipoprotein B mRNA editing enzyme catalytic subunit 2) Enables cytidine deaminase activity and identical protein binding activity. Involved in DNA demethylation. Acts upstream of or within cytidine to uridine editing. Predicted to be active in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

APOBEC2 links:

OARD1 (HGNC:21257): (O-acyl-ADP-ribose deacylase 1) The protein encoded by this gene is a deacylase that can convert O-acetyl-ADP-ribose to ADP-ribose and acetate, O-propionyl-ADP-ribose to ADP-ribose and propionate, and O-butyryl-ADP-ribose to ADP-ribose and butyrate. The ADP-ribose product is able to inhibit these reactions through a competitive feedback loop. [provided by RefSeq, Jul 2016]

The c.284C>T (p.A95V) alteration is located in exon 2 (coding exon 2) of the APOBEC2 gene. This alteration results from a C to T substitution at nucleotide position 284, causing the alanine (A) at amino acid position 95 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
