Abstract
Rare variants in the LMNA gene encoding nuclear lamin A/C are causal for more than a dozen diverse mendelian disorders. Defining the functional consequences of LMNA variants has been challenging given the pleiotropy of gene functions and potential pathogenic mechanisms. It is essential to develop trustworthy, scalable and rapidly deployable in vitro assays of function to enable timely assessment of missense variants that are being uncovered by high throughout next-generation sequencing.
