Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004788662 SCV005399708 likely benign Loeys-Dietz syndrome 2 2024-10-11 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.5, this variant is classified as Likely benign. Following criteria are met: 0103 - Loss of function and gain of function are mechanisms of disease in this gene and are associated with Loeys-Dietz syndrome 2 (MIM#610168). Gain of function has been demonstrated as a potential disease mechanism in patients with Loeys-Dietz syndrome 2, while loss of function has also been suggested for particular missense variants (PMIDs: 20301312, 15731757, 32528524, 28679693). (I) 0107 - This gene is associated with autosomal 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) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (v2, v3 and v4). (SP) 0708 - Other NMD-predicted variants comparable to the one identified in this case have conflicting previous evidence for pathogenicity. One other NMD-predicted variant (p.(Phe160Leufs*14)) has been reported in an individual with dysmorphic features and joint laxity (PMID: 31569402), many other NMD-predicted variants have been reported as VUS (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) 1205 - This variant has been shown to be maternally inherited (by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
