Genes affected

APOBEC3G (HGNC:17357): (apolipoprotein B mRNA editing enzyme catalytic subunit 3G) This gene is a member of the cytidine deaminase gene family. It is one of seven related genes or pseudogenes 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. The protein encoded by this gene catalyzes site-specific deamination of both RNA and single-stranded DNA. The encoded protein has been found to be a specific inhibitor of human immunodeficiency virus-1 (HIV-1) infectivity. [provided by RefSeq, Mar 2017]

The c.814G>T (p.D272Y) alteration is located in exon 6 (coding exon 6) of the APOBEC3G gene. This alteration results from a G to T substitution at nucleotide position 814, causing the aspartic acid (D) at amino acid position 272 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
