Genes affected
DCST1 (HGNC:26539): (DC-STAMP domain containing 1) This gene encodes a protein with a domain similar to one found in dendritic cells (PMID:11169400) which play a key role in antigen processing and display for immune responses. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]
DCST1-AS1 (HGNC:41147): (DCST1 antisense RNA 1)

The c.1369G>A (p.V457M) alteration is located in exon 13 (coding exon 12) of the DCST1 gene. This alteration results from a G to A substitution at nucleotide position 1369, causing the valine (V) at amino acid position 457 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
