Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002471675 SCV002769131 uncertain significance Blepharocheilodontic syndrome 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 VUS-3A. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with CDH1-related conditions, including blepharocheilodontic syndrome 1 (MIM#119580). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0212 - Non-canonical splice site variant without proven consequence on splicing (no functional evidence available). (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0505 - Abnormal splicing is predicted by in silico tools and affected nucleotide is highly conserved. (SP) 0600 - Variant is located in the annotated cadherin domain 3 (DECIPHER, PMID: 28301459). (I) 0705 - No comparable splice variants have previous evidence for pathogenicity. However, a missense variant affecting the same nucleotide position (c.1320G>T, p.(Lys440Asn)) has been observed as de novo in at least one individual with blepharocheilodontic syndrome 1 (MIM#119580) and may affect splicing (PMID: 28301459). There are also pathogenic reports for several other downstream variants in the canonical splice region (ClinVar). (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) 1102 - Strong phenotype match for this individual. (SP) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
