Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002272433 SCV001427109 pathogenic Alport syndrome 2020-07-02 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.3, this variant is classified as Pathogenic. Following criteria are met: 0103 - Dominant negative, caused by missense variants mostly glycine substitutions that affect the conformation of the protein, and loss of function, caused by either protein truncating and missense variants, are known mechanisms of disease in this gene and are associated with Alport syndrome (PMIDs: 24046192, 12028435). (I) 0110 - This gene is associated with X-linked dominant disease. (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 variants comparable to the one identified in this case have very strong previous evidence for pathogenicity (ClinVar, Decipher). (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) 1205 - This variant has been shown to be maternally inherited (LABID 18G003947). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
