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]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 29, 2019 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C55"). This variant has not been reported in the literature in individuals with DST-related conditions. ClinVar contains an entry for this variant (Variation ID: 579394). This variant is present in population databases (rs767768995, ExAC 0.001%). This sequence change replaces lysine with glutamic acid at codon 1692 of the DST protein (p.Lys1692Glu). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and glutamic acid. - |
