Genes affected

APOBEC3D (HGNC:17354): (apolipoprotein B mRNA editing enzyme catalytic subunit 3D) This gene is a member of the cytidine deaminase gene family. It is one of a group of related genes found in a cluster, thought to result from gene duplication, on chromosome 22. Members of the cluster encode proteins that are structurally and functionally related to the C to U RNA-editing cytidine deaminase APOBEC1 and inhibit retroviruses, such as HIV, by deaminating cytosine residues in nascent retroviral cDNA.

The c.431G>A (p.R144Q) alteration is located in exon 3 (coding exon 3) of the APOBEC3D gene. This alteration results from a G to A substitution at nucleotide position 431, causing the arginine (R) at amino acid position 144 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
