Genes affected

DCANP1 (HGNC:24459): (dendritic cell associated nuclear protein 1) This intronless gene is specifically expressed in dendritic cells (DCs), which are potent antigen-presenting cells involved in activating naive T cells to initiate antigen-specific immune response. The encoded protein is localized mainly in the perinucleus. One of the alleles (A/T) of this gene, that causes premature translation termination at aa 117, has been associated with an increased prevalence of major depression in humans.

TIFAB (HGNC:34024): (TIFA inhibitor) Involved in several processes, including animal organ morphogenesis; cranial nerve development; and hard palate morphogenesis. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

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

• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.864 is higher than 0.05.
