Alzheimer’s disease (AD) is a neurodegenerative condition in which amyloid plaques and neurofibrillary tangles accumulate in the brain. In addition to genetic factors, DNA damage and epigenetic alterations also play a key role in the pathogenesis and progression of this disease, altering gene expression, the functioning and maintenance of brain cells. DNA double-strand breaks (DSBs) and chromatin accessibility are two hallmarks of AD whose study could reveal new ways of approaching this disease.
Hypochondroplasia (HCH) is a skeletal dysplasia similar to achondroplasia (ACH) but with milder features, that affects particularly the ossification of proximal long bones of arms and legs. Around 70% to 80% of cases of HCH are caused by N540K alterations in the FGFR3 gene. At the recent 6th Annual Achondroplasia & Skeletal Dysplasia Research Conference, researchers from Tyra Biosciences Inc. presented preclinical proof-of-concept data of TYRA-300, an oral FGFR3-selective inhibitor in a model of HCH.
New single-step genome editing techniques that enable the insertion, inversion or deletion of long DNA sequences at specified genome positions have been demonstrated in bacteria.

New single-step genome editing techniques that enable the insertion, inversion or deletion of long DNA sequences at specified genome positions have been demonstrated in bacteria. The advance opens the door to the development of programmable methods for rearranging DNA, using recombinase enzymes guided by RNA. The two different approaches to using insertion sequences (IS) – some of the simplest and most compact mobile genetic elements – are described in two papers published in Nature and Nature Communications.
Variants in several subunits of the Mediator protein complex are responsible for MEDopathies, which present variable clinical manifestations and modes of inheritance. Researchers from Université de Paris Cité have investigated the role of MED16, a subunit of the evolutionary-conserved Mediator complex, in MEDopathies.
At the ESHG meeting in Berlin, a novel causative gene for Perrault syndrome was presented by a researcher from the University of Manchester. Perrault syndrome is a rare autosomal recessive disease characterized by sensorineural hearing loss and primary ovarian insufficiency.
Relay Therapeutics Inc. has disclosed three new programs from its existing preclinical pipeline, including two novel programs from its genetic disease portfolio and a potentially first-in-class NRAS-selective inhibitor.
Fibrodysplasia ossificans progressiva (FOP) is a rare and life-threatening genetic disease caused by gain-of-function mutations in the ALK2 gene, which encodes activin receptor-like kinase 2. Blueprint Medicines Corp. has elucidated the discovery of their ALK2 inhibitor BLU-782, which is now in phase II studies at Ipsen SA for the treatment of FOP.
