Description

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 Glass syndrome (MIM#612313). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to histidine. (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 high conservation. (I) 0602 - Variant is located in a hotspot region or cluster of pathogenic variants. The variant is located in the center region of CUT1 domain where previously reported pathogenic variants clustered (PMID: 28151491, DECIPHER). (SP) 0701 - Other missense variants comparable to the one identified in this case have very strong previous evidence for pathogenicity. p.(Arg389Cys) and p.(Arg389Leu) have been reported in many individuals with SATB2 -related neurodevelopmental disorder (PMIDs: 31021519, 28151491, ClinVar). (SP) 0802 - This variant has moderate previous evidence of pathogenicity in unrelated individuals. It has been reported as de novo in two individuals with global developmental delay or Glass syndrome (DECIPHER, PMID: 31302918). (SP) 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

Description

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. This variant disrupts the p.Arg389 amino acid residue in SATB2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 24884844, 28151491; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on SATB2 protein function. This missense change has been observed in individual(s) with Glass syndrome (PMID: 31302918). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 389 of the SATB2 protein (p.Arg389His).
