Generation of a FLNA knockout hESC line (WAe009-A-P) to model cardiac valvular dysplasia using CRISPR/Cas9

The FLNA gene encodes the cytoskeletal protein filamin A which plays a key role in the structure and function of the cardiac valves. Truncating FLNA mutations are associated with cardiac valvular dysplasia. To further understand the exact role of FLNA in this disease, we have generated a human FLNA...

Description
Summary:The FLNA gene encodes the cytoskeletal protein filamin A which plays a key role in the structure and function of the cardiac valves. Truncating FLNA mutations are associated with cardiac valvular dysplasia. To further understand the exact role of FLNA in this disease, we have generated a human FLNA knockout cell line from H9 using CRISPR/Cas9 technology in this study. This cell line WAe009-A-P has a 2 bp deletion in the exon 2 of FLNA gene which resulted in a frameshift in the translation of FLNA and no FLNA protein was detected in this cell line. Moreover, WAe009-A-P also expressed pluripotency markers, had a normal female karyotype (46XX) and maintained the ability to differentiate into the three germ layers in vitro.
