Genes affected

DSE (HGNC:21144): (dermatan sulfate epimerase) The protein encoded by this gene is a tumor-rejection antigen. It is localized to the endoplasmic reticulum and functions to convert D-glucuronic acid to L-iduronic acid during the biosynthesis of dermatan sulfate. This antigen possesses tumor epitopes capable of inducing HLA-A24-restricted and tumor-specific cytotoxic T lymphocytes in cancer patients and may be useful for specific immunotherapy. Mutations in this gene cause inmusculocontractural Ehlers-Danlos syndrome. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 9, and a paralogous gene exists on chromosome 18. [provided by RefSeq, Apr 2016]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

A variant of uncertain significance has been identified in the DSE gene. The V633M variant has not been published as pathogenic or been reported as benign to our knowledge. This variant is observed in 110/16512 (0.7%) alleles from individuals of South Asian ancestry, including one homozygous individual, in the Exome Aggregation Consortium (ExAC) dataset (Lek et al., 2016; Exome Variant Server). The V633M variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is only conserved in mammals. Finally, in silico analysis suggests that this variant likely does not alter the protein structure/function. -
