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.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.359T>C (p.L120S) alteration is located in exon 3 (coding exon 3) of the APOBEC3D gene. This alteration results from a T to C substitution at nucleotide position 359, causing the leucine (L) at amino acid position 120 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
