Genes affected
DST (HGNC:1090): (dystonin) This gene encodes a member of the plakin protein family of adhesion junction plaque proteins. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene, but the full-length nature of some variants has not been defined. It has been reported that some isoforms are expressed in neural and muscle tissue, anchoring neural intermediate filaments to the actin cytoskeleton, and some isoforms are expressed in epithelial tissue, anchoring keratin-containing intermediate filaments to hemidesmosomes. Consistent with the expression, mice defective for this gene show skin blistering and neurodegeneration. [provided by RefSeq, Mar 2010]

Hereditary sensory and autonomic neuropathy type 6;C3809470:Epidermolysis bullosa simplex 3, localized or generalized intermediate, with BP230 deficiency Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 29, 2023This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 2008 of the DST protein (p.Leu2008Pro). This variant is present in population databases (rs146392434, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with DST-related conditions. ClinVar contains an entry for this variant (Variation ID: 541455). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
