Victorian Clinical Genetics Services, Murdoch Childrens Research Institute	RCV002470424	SCV002767850	likely pathogenic	Neurodevelopmental disorder with hypotonia, seizures, and absent language	2020-10-19	criteria provided, single submitter	clinical testing	Based on the classification scheme VCGS_Germline_v1.3.3, this variant is classified as Likely pathogenic. Following criteria are met: 0105 - The mechanism of disease for this gene is not clearly established. (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from serine to alanine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0600 - Variant is located in the annotated HECT domain (PDB; NCBI). (I) 0704 - Another missense variant comparable to the one identified in this case has limited previous evidence for pathogenicity. p.(Ser1504Tyr) has previously been reported de novo in at least one patient with HECW2-related disease (ClinVar) (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
