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.

The c.697C>G (p.L233V) alteration is located in exon 1 (coding exon 1) of the DCANP1 gene. This alteration results from a C to G substitution at nucleotide position 697, causing the leucine (L) at amino acid position 233 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
