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]

Ambry Genetics

Apr 20, 2024

The c.768A>G (p.I256M) alteration is located in exon 8 (coding exon 7) of the DCST1 gene. This alteration results from a A to G substitution at nucleotide position 768, causing the isoleucine (I) at amino acid position 256 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
