RCV002272973 | SCV002557479 | pathogenic | Severe intellectual disability-progressive spastic diplegia syndrome | 2022-06-24 | 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 neurodevelopmental disorder with spastic diplegia and visual defects (MIM#615075), and exudative vitreoretinopathy 7 (MIM#617572). However, somatic variants with a gain of function mechanism have been reported to cause cancer (OMIM). (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 (both v2 and v3). (SP) 0701 - Other NMD-predicted variants comparable to the one identified in this case have very strong previous evidence for pathogenicity. These variants have been reported many times as pathogenic (PMID: 35099645, DECIPHER). (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) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed, by trio analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
