Abstract excerpt
Disease-associated variants can lead to variable phenotypic outcomes in neurodevelopmental disorders, but the biological mechanisms underlying this variability remain poorly understood. Here, we develop a framework to investigate this phenomenon using the 16p12.1 deletion as a paradigm of variable expressivity. Using induced pluripotent stem cell models from affected families and CRISPR-edited lines with the...
