RCV002471347 | SCV002767310 | pathogenic | Dent disease type 1 | 2021-05-06 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Dent disease (MIM#300009). (I) 0115 - Variants in this gene are known to have variable expressivity. The phenotype can be variable within and between families (PMID: 28580211). (I) 0109 - This gene is associated with X-linked recessive disease. Dent disease (MIM#300009) is now the generally accepted name for a group of hereditary tubular disorders including X-linked recessive nephrolithiasis type I (MIM#310468), hypophosphataemic rickets (MIM#300554), and low molecular weight proteinuria with hypercalciuric nephrocalcinosis (MIM#308990) (PMID: 12637640). Dent disease (MIM#300009) mainly affects males, however female carriers may show a milder phenotype (PMID: 28580211). (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0253 - This variant is hemizygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0701 - Other NMD-predicted variants comparable to the one identified in this case have very strong previous evidence for pathogenicity. Many other loss of function variants have previously been reported as pathogenic in individuals with Dent disease (MIM#300009) (ClinVar). (SP) 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 |
