Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002471036 SCV002766610 pathogenic Osteogenesis imperfecta type I 2022-03-31 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: 0103 - Dominant negative and loss of function are known mechanisms of disease in this gene and are associated with Osteogenesis imperfect types I-IV, and other conditions (OMIM). Variants resulting in a truncated protein are known to have a loss of function effect on protein, while missense variants affecting the G-X-Y of a triple helix motif, have a dominant negative effect (PMID:27509835, PMID:12362985). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0115 - Variants in this gene are known to have variable expressivity (GeneReviews). (I) 0200 - Variant is predicted to result in a missense amino acid change from glycine to cysteine. (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 collagen domain within a GXY motif of the triple helix (DECIPHER). (SP) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been reported in at least 5 patients with osteogenesis imperfecta (PMIDs: 17078022, 25742658, 27509835, 29499418; LOVD-Osteogenesis Imperfecta Variant Database). (SP) 1102 - Strong phenotype match for this individual. (SP) 1204 - This variant has been shown to be de novo in the proband (parental status not tested but assumed) (by trio analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
