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]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.45).
• BP6: Variant 6-56616183-T-C is Benign according to our data. Variant chr6-56616183-T-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 357549.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Likely_benign=1, Uncertain_significance=1}.
• BP7: Synonymous conserved (PhyloP=0.616 with no splicing effect.
• BS2: High Homozygotes in GnomAdExome at 2 AR gene
