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 -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.59).
BP6
Variant 6-56640377-T-A is Benign according to our data. Variant chr6-56640377-T-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 357617.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1, Benign=2}. Variant chr6-56640377-T-A is described in Lovd as [Benign]. Variant chr6-56640377-T-A is described in Lovd as [Likely_benign].
BP7
Synonymous conserved (PhyloP=-0.268 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.00314 (4592/1461828) while in subpopulation MID AF= 0.0147 (85/5766). AF 95% confidence interval is 0.0132. There are 42 homozygotes in gnomad4_exome. There are 2577 alleles in male gnomad4_exome subpopulation. Median coverage is 34. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 42 AR gene
