Abstract(s)

Mutations in the Budding uninhibited by benzimidazoles (BUB1) gene were recently associated with neurodevelopmental disorders (Carvalhal et al., 2022). Here, we describe the generation and characterization of two induced pluripotent stem cells (iPSC) clones from a young female with microcephaly. The patient carried two variants in the BUBfibroblast gene (OMIM # 602452), one (c.[2197dupG]; p.[D732fs*11]) paternally inherited and one (c.[2625+1G>A]; p.[V822_L875del] maternally inherited. The generated clones exhibit a normal karyotype (UALGi003-A) and trisomy 8 (UALGi003-B), express pluripotency markers, and differentiate into trilineage cells in vitro. These cell lines can be used to study neurodevelopment and the processes of chromosome segregation.
