Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002272805 SCV002557186 uncertain significance Hemorrhage, intracerebral, susceptibility to 2022-09-02 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3A. Following criteria are met: 0103 - Dominant negative and loss of function are known mechanisms of disease in this gene and are associated with COL4A1-related disorders. Missense variants affecting the glycine of the triple helix of collagen genes typically exert a dominant-negative effect however, functional studies proving this for COL4A1 is currently lacking (PMID:16159887). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0112 - The condition associated with this gene has incomplete penetrance (PMID:21625620, 30413629). (I) 0200 - Variant is predicted to result in a missense amino acid change from glycine to serine. (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 is located in the well-established functional triple helical collagen domain. It affects the G of GXY repeat however, it is the last one in the region (UCSC, 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
