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.

Nov 14, 2024

The c.124T>C (p.S42P) alteration is located in exon 1 (coding exon 1) of the DCANP1 gene. This alteration results from a T to C substitution at nucleotide position 124, causing the serine (S) at amino acid position 42 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
