RCV004788653 | SCV005399685 | likely pathogenic | Alport syndrome | 2024-10-09 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Likely pathogenic. Following criteria are met: 0103 - Dominant negative and loss of function are known mechanisms of disease in this gene and are associated with Alport syndrome (MONDO:0018965), COL4A3-related. Glycine changes that are part of a G-X-Y repeat in the triple helix of a collagen domain are known to have a dominant negative effect (PMID: 12028435). (I) 0108 - This gene is associated with both recessive and dominant disease, Alport syndrome 3B (MIM#620536) and Alport syndrome 3A (MIM#104200), respectively (OMIM). (I) 0200 - Variant is predicted to result in a missense amino acid change from glycine to arginine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0601 - Variant affects one of the glycine residues of the well-established functional Gly-X-Y motif in the collagen triple helical domain (DECIPHER). (SP) 0705 - No comparable missense 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 |
