The analysis revealed that 34% of strains belonged to the Delhi/CAS (TbD1-) lineage, 32% had unknown patterns (27 TbD1-, 5 TbD1+), 18% were of Beijing genotype (TbD1-) and 11% were of EAI lineages (TbD1+).
These are the first reported cases with well-characterized CAS in the 16p11.2 syndrome literature and the first report of this microdeletion in CAS genetics research.
