3billion | RCV001809974 | SCV002058991 | uncertain significance | Woolly hair-skin fragility syndrome | 2022-01-03 | criteria provided, single submitter | clinical testing | Same nucleotide change resulting in same amino acid change has been previously reported to be associated with DSP related disorder (PMID:26148547, PS1_P). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.646, PP3_P). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000016, PM2_M). Therefore, this variant is classified as uncertain significance according to the recommendation of ACMG/AMP guideline. |

RCV003532368 | SCV004363299 | uncertain significance | Cardiomyopathy | 2022-06-15 | criteria provided, single submitter | clinical testing | This missense variant replaces proline with leucine at codon 498 of the DSP protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in a large family segregating with an autosomal recessive form of hair loss disorder (PMID: 26148547). There was no history of sudden death in this family and the three affected homozygotes were reported to be normal in cardiac auscultation and echocardiographic evaluation. This variant has been identified in 4/251448 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in autosomal dominant heart disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
