A prospective trial comparing programmable targeted long-read sequencing and short-read genome sequencing for genetic diagnosis of cerebellar ataxia.

The cerebellar ataxias (CAs) are a heterogeneous group of disorders characterized by progressive incoordination. Seventeen repeat expansion (RE) loci have been identified as the primary genetic cause and account for >80% of genetic diagnoses. Despite this, diagnostic testing is limited and inefficient, often utilizing single gene assays.

Giant RNA genomes: Roles of host, translation elongation, genome architecture, and proteome in nidoviruses.

Positive-strand RNA viruses of the order have the largest known RNA genomes of vertebrate and invertebrate viruses with 36.7 and 41.1 kb, respectively.

The translational landscape of HIV-1 infected cells reveals key gene regulatory principles.

Human immunodeficiency virus-1 (HIV-1) uses a number of strategies to modulate viral and host gene expression during its life cycle. To characterize the transcriptional and translational landscape of HIV-1 infected cells, we used a combination of ribosome profiling, disome sequencing and RNA sequencing. We show that HIV-1 messenger RNAs are efficiently translated at all stages of infection, despite evidence for a substantial decrease in the translational efficiency of host genes that are implicated in host cell translation.

Selectively expressed RNA molecules as a versatile tool for functionalized cell targeting.

Targeting of diseased cells is one of the most urgently needed prerequisites for a next generation of potent pharmaceuticals. Different approaches pursued fail mainly due to a lack of specific surface markers. Developing an RNA-based methodology, we can now ensure precise cell targeting combined with selective expression of effector proteins for therapy, diagnostics or cell steering.

Genetic counseling workforce diversity, inclusion, and capacity in Australia and New Zealand.

Purpose: To understand diversity, inclusion, and capacity of genetic counselors (GCs) in Australasia (Australia and New Zealand).

Methods: Individuals with or working toward a GC qualification in Australasia were invited to complete an online survey, between November 2022 and March 2023. Quantitative data were analyzed using descriptive statistics, 1-sample proportion -tests, 2-sample -tests, and χ tests.
