Genes affected

APOBEC4 (HGNC:32152): (apolipoprotein B mRNA editing enzyme catalytic polypeptide like 4) This gene encodes a member of the AID/APOBEC family of polynucleotide (deoxy)cytidine deaminases, which convert cytidine to uridine. Other AID/APOBEC family members are involved in mRNA editing, somatic hypermutation and recombination of immunoglobulin genes, and innate immunity to retroviral infection.

RGL1 (HGNC:30281): (ral guanine nucleotide dissociation stimulator like 1) Predicted to be involved in regulation of catalytic activity. Predicted to be located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.015645653).
• BS2: High Homozygotes in GnomAdExome4 at 3 AR gene
