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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=8.9006903E-7).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.786 is higher than 0.05.
