Despite the growing demand for genomic data and the falling price of genome sequencing, costs continue to restrain its use. Single Technologies, which is developing a three-dimensional approach to sequencing, believes it can cut the cost to just $10 per genome for consumables. That’s a drop from estimates of about $600 today. We spoke to Johan Strömqvist, CEO and founder of Single Technologies and...

Nonsense mutations prematurely end the translation of a gene into protein and can result in a serious deficiency. About 10 to 15 percent of inherited genetic diseases involve nonsense mutations. Alltrna is developing transfer RNA therapies designed to correct the problem in protein synthesis caused by these aberrations. What’s particularly exciting about the approach is that a single therapy has t...

Effie Parks is well known in the rare disease community as both a patient advocate and host of the Once Upon a Gene podcast.
