<jats:p>Characterized by developmental delay with severe speech delay, dental anomalies, cleft palate, skeletal abnormalities, and behavioral difficulties, SATB2-associated syndrome (SAS) is caused by pathogenic variants in SATB2. The SAS phenotype range of severity has been documented previously in large series. Using data from the SAS registry, we present the SAS severity score, a comprehensive scoring rubric that encompasses 15 different individual neurodevelopmental and systemic features. Higher (more severe) systemic and total (sum of neurodevelopmental and systemic scores) scores were seen for null variants located after amino acid 350 (the start of the CUT1 domain), the recurrent missense Arg389Cys variant (<jats:inline-formula> <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mi>n</mi> <mo>=</mo> <mn>10</mn> </math> </jats:inline-formula>), intragenic deletions, and larger chromosomal deletions. The Arg389Cys variant had the highest cognitive, verbal, and sialorrhea severity scores, while large chromosomal deletions had the highest expressive, ambulation, palate, feeding and growth, neurodevelopmental, and total scores. Missense variants not located in the CUT1 or CUT2 domain scored lower in several subcategories. We conclude that the SAS severity score allows quantitative phenotype morbidity description that can be used in routine clinical counseling. Further refinement and validation of the SAS severity score are expected over time. All data from this project can be interactively explored in a new portal.</jats:p>

<jats:title>Abstract</jats:title> <jats:sec> <jats:title>Motivation</jats:title> <jats:p>Pathogenic copy-number variants (CNVs) can cause a heterogeneous spectrum of rare and severe disorders. However, most CNVs are benign and are part of natural variation in human genomes. CNV pathogenicity classification, genotype–phenotype analyses, and therapeutic target identification are challenging and time-consuming tasks that require the integration and analysis of information from multiple scattered sources by experts.</jats:p> </jats:sec> <jats:sec> <jats:title>Results</jats:title> <jats:p>Here, we introduce the CNV-ClinViewer, an open-source web application for clinical evaluation and visual exploration of CNVs. The application enables real-time interactive exploration of large CNV datasets in a user-friendly designed interface and facilitates semi-automated clinical CNV interpretation following the ACMG guidelines by integrating the ClassifCNV tool. In combination with clinical judgment, the application enables clinicians and researchers to formulate novel hypotheses and guide their decision-making process. Subsequently, the CNV-ClinViewer enhances for clinical investigators’ patient care and for basic scientists’ translational genomic research.</jats:p> </jats:sec> <jats:sec> <jats:title>Availability and implementation</jats:title> <jats:p>The web application is freely available at https://cnv-ClinViewer.broadinstitute.org and the open-source code can be found at https://github.com/LalResearchGroup/CNV-clinviewer.</jats:p> </jats:sec>
