Frequent somatic mosaicism in T lymphocyte subsets in individuals with and without multiple sclerosis by Lies Van Horebeek, Nina Dedoncker, Bénédicte Dubois, Bénédicte Dubois, An Goris

“…BackgroundSomatic variants are variations in an individual’s genome acquired after the zygotic stadium and result from mitotic errors or not (fully) repaired DNA damage.ObjectivesTo investigate whether somatic mosaicism in T lymphocyte subsets is enriched early in multiple sclerosis (MS).MethodsWe identified somatic variants with variant allele fractions ≥1% across the whole exome in CD4+ and CD8+ T lymphocytes of 21 treatment-naive MS patients with &lt;5 years of disease duration and 16 partially age-matched healthy controls. …”
