A Danish study has improved the diagnosis of rare genetic diseases using CRISPR technology.

CRISPR is used to activate genes in accessible cells like skin and blood, allowing researchers to examine messenger RNA assembly.

Previously, 19% of disease-associated genes were inactive in such tissues, hindering disease investigation.

CRISPR can now activate these genes, opening avenues for analysis, diagnosis and understanding of genetic diseases.

The method is fast and can yield results within weeks.

This advancement can shorten diagnostic processes, reduce uncertainty for patients and enable timely treatment.
