Genes affected

DCSTAMP (HGNC:18549): (dendrocyte expressed seven transmembrane protein) This gene encodes a seven-pass transmembrane protein that is primarily expressed in dendritic cells. The encoded protein is involved in a range of immunological functions carried out by dendritic cells. This protein plays a role in osteoclastogenesis and myeloid differentiation. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Mar 2012]

DCSTAMP (HGNC:):

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.007275045).
• BS2: High Homozygotes in GnomAd4 at 13 AR gene
