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

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DST. . Gene score misZ 2.2208 (greater than the threshold 3.09). Trascript score misZ 3.9149 (greater than threshold 3.09). GenCC has associacion of gene with hereditary sensory and autonomic neuropathy type 6, epidermolysis bullosa simplex 3, localized or generalized intermediate, with BP230 deficiency.
BP4
Computational evidence support a benign effect (MetaRNN=0.0032327473).
BP6
Variant 6-56640283-G-C is Benign according to our data. Variant chr6-56640283-G-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 357616.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1, Benign=2}. Variant chr6-56640283-G-C is described in Lovd as [Likely_benign].
BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.00275 (4022/1461852) while in subpopulation SAS AF= 0.0102 (877/86258). AF 95% confidence interval is 0.00961. There are 21 homozygotes in gnomad4_exome. There are 2154 alleles in male gnomad4_exome subpopulation. Median coverage is 34. This position pass quality control queck.
BS2
