<p>This is an observational study which examined the phylogenetic evolution of somatic clonal mutations in <a href="https://www.ncbi.nlm.nih.gov/gene/25913">POT1</a> mutation carriers. Two individuals with telomere syndromes who carry a heterozygous germline <a href="https://www.ncbi.nlm.nih.gov/gene/25913">POT1</a> p.R273Q variant and one related control who did not carry this variant were studied. Single cell hematopoietic colonies were derived from peripheral blood mononuclear isolates. These colonies were analyzed by whole genome sequencing (WGS) and phylogenetic trees were reconstructed accordingly. Phylogenetic reconstruction of somatic mutations show clonality is increased among <a href="https://www.ncbi.nlm.nih.gov/gene/25913">POT1</a> p.R273Q mutation carriers and co-occurs with known clonal hematopoiesis driver mutations, including <a href="https://www.ncbi.nlm.nih.gov/gene/1788">DNMT3A</a> and/or <a href="https://www.ncbi.nlm.nih.gov/gene/3717">JAK2</a>. </p>
