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)

Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.1613C>T (p.P538L) alteration is located in exon 15 (coding exon 14) of the DCST1 gene. This alteration results from a C to T substitution at nucleotide position 1613, causing the proline (P) at amino acid position 538 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
