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 was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.67).

BP6

Variant 6-56618142-G-A is Benign according to our data. Variant chr6-56618142-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 357562.

BP7

Synonymous conserved (PhyloP=-1.71 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000736 (112/152172) while in subpopulation NFE AF = 0.00128 (87/68006). AF 95% confidence interval is 0.00106. There are 1 homozygotes in GnomAd4. There are 49 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
