The variant received -4 classification points (ACGS-UK Somatic Oncogenicity v2025). B1_Strong

The NM_002119.4(HLA-DOA):c.82+473C>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.619 (AC=94,082) in the gnomAD database across 151,942 control chromosomes, including 29,621 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.746. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

HLA-DOA (HGNC:4936): (major histocompatibility complex, class II, DO alpha) HLA-DOA belongs to the HLA class II alpha chain paralogues. HLA-DOA forms a heterodimer with HLA-DOB. The heterodimer, HLA-DO, is found in lysosomes in B cells and regulates HLA-DM-mediated peptide loading on MHC class II molecules. In comparison with classical HLA class II molecules, this gene exhibits very little sequence variation, especially at the protein level. [provided by RefSeq, Jul 2008]
