We are pioneering a new way to treat the underlying causes of severe genetic diseases by precisely upregulating protein expression. We are developing novel antisense oligonucleotide, or ASO, medicines that target ribonucleic acid, or RNA, and modulate precursor-messenger RNA, or pre-mRNA, splicing to upregulate protein expression where needed and with appropriate specificity to near normal levels. We utilize our proprietary technology platform, Targeted Augmentation of Nuclear Gene Output, or TANGO, to design ASOs to upregulate the expression of protein by individual genes in a patient.
