Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002471373 SCV002767364 uncertain significance Ataxia - intellectual disability - oculomotor apraxia - cerebellar cysts syndrome 2021-05-06 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3C. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Poretti-Boltshauser syndrome (MIM#615960). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from phenylalanine to leucine. (I) 0252 - This variant is homozygous. (I) 0304 - Variant is present in gnomAD <0.01 for a recessive condition (1 heterozygote, 0 homozygotes). (SP) 0504 - Same amino acid change has been observed in placental mammals. (SB) 0600 - Variant is located in the annotated Laminin G-like 5 domain (Uniprot). (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (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) 1209 - This variant has been shown to be both maternally and paternally inherited (biallelic) (by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
GeneDx RCV004779352 SCV005392470 uncertain significance not provided 2024-05-03 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
