chr6-7585731-GGGGTCCCGCTCC-G

Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 2P and 8B. PM4BP6_Very_Strong

The NM_004415.4(DSP):​c.8472_8483delGTCCCGCTCCGG​(p.Ser2825_Gly2828del) variant causes a disruptive inframe deletion change. The variant allele was found at a frequency of 0.0000409 in 1,612,030 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. G2824G) has been classified as Benign.

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.

Ser2843_Arg2846del in exon 24 of DSP: This variant is not expected to have clini cal significance because it has been identified in 1.45% (62/4266) of African Am erican chromosomes from a broad population by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/). This in-frame deletion of four amino acids occurs within a section of repeating amino acids, which can result from several different DNA deletions, and is present in mammals (dolphin, opossum, and platy pus) and other evolutionarily distant species. -

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
