Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP2BP4_Moderate

The NM_001374736.1(DST):ā€‹c.3949A>Gā€‹(p.Ile1317Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000062 in 1,613,926 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I1317F) has been classified as Uncertain significance.

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 Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
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=0.1857507).
