RISPR/Cas9 technology generated a frameshift 2-bp deletion in exon 7 from position +49,580 to +49,581 relative to the translation start site. Exon 7 is the most commonly mutated exon in Marshall-Smith Syndrome patients. The frameshift introduced a premature stop codon and led to the production of intermediate levels of mutant protein. MEFs express the mutant long isoform (315 bp) and the wild-type short isoform lacking exon 7 (194 bp). (J:343087)
