Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002472245 SCV002769346 pathogenic Lowe syndrome 2020-05-26 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.1.1, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss-of-function is a known mechanism of disease for this gene. (N) 0109 - This gene is known to be associated with X-linked recessive disease. (N) 0205 - Variant is located at the end of exon 23, therefore it is predicted to affect splicing and result in a truncated protein with less than 1/3 of the protein affected (exon 23 of 24). (P) 0210 - Splice site variant (non-canonical) proven to abolish the donor splice site, resulting in skipping of exon 23 and a truncated protein (PMID: 29300302). (N) 0253 - Variant is hemizygous. (N) 0301 - Variant is absent from gnomAD. (P) 0505 - Abnormal splicing is predicted by in silico tools and affected nucleotide is highly conserved. (P) 0600 - Variant results in truncation of an annotated domain, RhoGAP domain (PDB, PMID: 21031565). (N) 0703 - Comparable variants have moderate previous evidence for pathogenicity. A different variant c.2581G>C, has been shown to result in the same truncated protein and has been reported pathogenic in individuals with Lowe syndrome (PMID: 25480730). Multiple other protein truncating variants have been reported pathogenic in Lowe syndrome (ClinVar). (P) 0801 - Strong previous evidence of pathogenicity in unrelated individuals. The variant has been previously reported in patients with Lowe syndrome (PMID: 21031565, 25305077, 27059748). (P) 1205 - Variant is maternally inherited. (N) Legend: (P) - Pathogenic, (N) - Neutral, (B) - Benign
