Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002471462 SCV002768146 uncertain significance Cutis laxa with severe pulmonary, gastrointestinal and urinary anomalies 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. The following criteria are met: 0102 - Loss of function is a mechanism of disease in this gene and is associated with cutis laxa type IC (MIM#613177). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0211 - Canonical splice site variant without proven consequence on splicing (no functional evidence available). (SP) 0219 - This variant is non-coding in an alternative transcript. The transcript used in this analysis is well reported in the literature (PMID: 25882708). (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0311 - An alternative nucleotide change at the same canonical splice site is present in gnomAD (v2) (c.76-1G>A; 2 heterozygotes, 0 homozygotes). (I) 0505 - Abnormal splicing is predicted by in silico tools and affected nucleotide is highly conserved. (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) 0705 - No comparable canonical splice site variants at this splice junction have previous evidence for pathogenicity. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
