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.

Oct 06, 2021

The c.173C>T (p.P58L) alteration is located in exon 2 (coding exon 2) of the APOBEC3D gene. This alteration results from a C to T substitution at nucleotide position 173, causing the proline (P) at amino acid position 58 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
