Variant 22-39100307-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_181773.5(APOBEC3H):c.29G>A(p.Arg10His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000249 in 1,604,180 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R10C) has been classified as Uncertain significance.

Genes affected

APOBEC3H (HGNC:24100): (apolipoprotein B mRNA editing enzyme catalytic subunit 3H) This gene encodes a member of the apolipoprotein B mRNA-editing enzyme catalytic polypeptide 3 family of proteins. The encoded protein is a cytidine deaminase that has antiretroviral activity by generating lethal hypermutations in viral genomes. Polymorphisms and alternative splicing in this gene influence its antiretroviral activity and are associated with increased resistence to human immunodeficiency virus type 1 infection in certain populations. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Oct 2009]

Ambry Genetics

Mar 20, 2023

The c.29G>A (p.R10H) alteration is located in exon 2 (coding exon 1) of the APOBEC3H gene. This alteration results from a G to A substitution at nucleotide position 29, causing the arginine (R) at amino acid position 10 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
