研究领域

There are more than 7,000 distinct rare human genetic diseases that collectively affect one in twelve people. Unfortunately, most have no treatments and about one third of patients die in childhood. The small number of patients with each disease (typically fewer than 1 in 2,000) makes it difficult to study disease biology and develop disease-specific therapies. However, about 10% of patients share a common mutation type: nonsense mutations. These mutations change an amino acid codon to a premature termination codon (PTC), resulting in truncated and non-functional protein. Nonsense mutations also account for about 10% of mutations in tumor suppressor genes in cancer. Restoring function of the mutated gene is a key treatment goal for rare genetic diseases and cancer. Chemicals that enable translational bypass of a PTC, termed PTC readthrough, allow production of full-length protein and offer the possibility of using the same treatment for many patients with different genetic diseases or cancers. Our research is focused on discovering chemicals that induce or promote PTC readthrough and developing them into treatments.
