RCV004788535 | SCV005398215 | uncertain significance | Polycystic kidney disease, adult type | 2024-10-10 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.5, this variant is classified as VUS-3B. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with polycystic kidney disease 1 (MIM#173900. (I) 0107 - This gene is associated with autosomal dominant disease. Polycystic kidney disease 1 (MIM#173900) is predominantly caused by monoallelic variants, with rare reports of biallelic variants causing disease (OMIM). (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to proline. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (v2, v3 and v4). (SP) 0309 - Multiple alternative amino acid changes at the same position have been observed in gnomAD (v4) (highest allele count: 501 heterozygotes, 2 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0600 - Variant is located in the annotated PLAT/LH2 domain (DECIPHER). (I) 0708 - Another missense variant comparable to the one identified in this case has conflicting previous evidence for pathogenicity. p.(Arg3183Gln) has been reported twice as a VUS and once as likely benign (ClinVar). This variant has been referred to as an ultra low penetrant or hypomorphic allele (PMID: 29038287). (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 |
