RCV004788212 | SCV005398680 | uncertain significance | Dilated cardiomyopathy 1G | 2022-06-24 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3B. Following criteria are met: 0102 - Loss of function is known mechanism of disease in this gene. In addition, dominant-negative is also a suggested mechanism. (PMID: 25589632). (I) 0108 - This gene is associated with both recessive and dominant disease (OMIM). (I) 0112 - The condition associated with this gene has incomplete penetrance. Variants in this gene that result in a premature truncating codon (PTC) are known to have reduced penetrance in dilated cardiomyopathy (PMID: 25589632). (I) 0211 - Canonical splice site variant without proven consequence on splicing (no functional evidence available). This variant is located within a region containing three tandem repeats of nine exons that share 99% DNA sequence homology among them (PMID: 29792937). (SP) 0219 - This variant is non-coding in an alternative transcript. It is a canonical splice variant in three of the transcripts - the meta transcript NM_001267550.1, the skeletal muscle-predominant N2A isoform NM_133378.4 and the adult cardiac N2BA isoform NM_001256850.1. (I) 0256 - Zygosity of this variant could not be unambiguously determined. Due to the high degree of DNA sequence homology in this region (PMID: 29792937), this assay could not confirm the exact zygosity and location of this variant. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). However, the sequencing coverage in this region is very low. (SP) 0508 - In silico predictions for abnormal splicing are conflicting. Abnormal splicing is predicted by in silico tool however the affected nucleotide is poorly conserved. (I) 0705 - No comparable splice site variants have previous evidence for pathogenicity. (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
