Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_004415.4(DSP):​c.2866A>T​(p.Asn956Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000267 in 1,611,160 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N956S) has been classified as Uncertain significance.

Genes affected
DSP (HGNC:3052): (desmoplakin) This gene encodes a protein that anchors intermediate filaments to desmosomal plaques and forms an obligate component of functional desmosomes. Mutations in this gene are the cause of several cardiomyopathies and keratodermas, including skin fragility-woolly hair syndrome. Alternative splicing results in multiple transcript variants.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.015366048).
BP6
Variant 6-7577031-A-T is Benign according to our data. Variant chr6-7577031-A-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 44887.
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000656 (10/152352) while in subpopulation EAS AF = 0.00173 (9/5190). AF 95% confidence interval is 0.000904. There are 0 homozygotes in GnomAd4. There are 4 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
