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]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.67).
BP6
Variant 6-56618028-G-A is Benign according to our data. Variant chr6-56618028-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 474534.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.759 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0036 (548/152270) while in subpopulation AFR AF = 0.0126 (525/41556). AF 95% confidence interval is 0.0117. There are 3 homozygotes in GnomAd4. There are 260 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 3 AR gene
