Labcorp Genetics (formerly Invitae), Labcorp RCV000648315 SCV000770129 likely pathogenic Rett syndrome, congenital variant 2017-10-31 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). This variant has been observed to be de novo in an individual affected with FOXG1-related disease (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with aspartic acid at codon 232 of the FOXG1 protein (p.Asn232Asp). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and aspartic acid.
Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV000648315 SCV005086512 pathogenic Rett syndrome, congenital variant 2023-07-17 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 Rett syndrome, congenital variant (MIM#613454). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from asparagine to aspartic acid. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0603 - Missense variant in a region that is highly intolerant to missense variation (high constraint region in DECIPHER). (SP) 0703 - Other missense variants comparable to the one identified in this case have moderate previous evidence for pathogenicity. Three alternative amino acid changes at the same position have been classified as pathogenic in ClinVar and/or observed in individals with Rett-like conditions/movement disorders (PMIDs: 28851325, 27029630, 26993267). (SP) 0802 - This variant has moderate previous evidence of pathogenicity in unrelated individuals. This variant has been classified as likely pathogenic in ClinVar by a clinical laboratory who observed it as de novo in an individual with a FOXG1-related condition. (SP) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1207 - Parental origin of the variant is unresolved. Duo analysis has shown that this variant is not maternally inherited; however, a sample from this individual's father has not been tested. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
