Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002471504 SCV002768229 pathogenic Exudative vitreoretinopathy 1 2022-02-02 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: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with exudative vitreoretinopathy 1 and retinopathy of prematurity (MIM#133780). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0115 - Variants in this gene are known to have variable expressivity. There is a large degree of intrafamilial variability, and asymptomatic heterozygous individuals have been reported (OMIM, PMID: 19324841). (I) 0204 - Variant is predicted to result in a truncated protein (premature termination codon is NOT located at least 54 nucleotides upstream of the final exon-exon junction) with at least 1/3 of the protein sequence affected. (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0600 - Variant is predicted to disrupt part of the Fz domain and the entire Frizzled/Smoothened family membrane region (DECIPHER). (I) 0701 - Other premature termination variants comparable to the one identified in this case have very strong previous evidence for pathogenicity. The p.(Phe82Alafs*54) variant and many premature termination variants located downstream have been reported in individuals with familial exudative vitreoretinopathy or as likely pathogenic/pathogenic (PMIDs: 17093393, 31827910; ClinVar). (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 (by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
