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 -21 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.47).

BP6

Variant 6-56616969-C-T is Benign according to our data. Variant chr6-56616969-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 474541.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr6-56616969-C-T is described in Lovd as [Likely_benign].

BP7

Synonymous conserved (PhyloP=0.157 with no splicing effect.

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000598 (91/152288) while in subpopulation SAS AF= 0.0189 (91/4818). AF 95% confidence interval is 0.0158. There are 2 homozygotes in gnomad4. There are 75 alleles in male gnomad4 subpopulation. This position pass quality control queck.

BS2

High Homozygotes in GnomAd at 2 AR gene
