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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2024The c.487C>T (p.R163C) alteration is located in exon 6 (coding exon 5) of the DCST1 gene. This alteration results from a C to T substitution at nucleotide position 487, causing the arginine (R) at amino acid position 163 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
