As previously reported by our group, FBRSL1-associated syndrome shares noticeable clinical overlap with AUTS2 syndrome, another neurodevelopmental disorder associated with developmental delay, autistic features, epilepsy, microcephaly, and additional features like short stature, and craniofacial dysmorphisms (Beunders et al. 2013; Hori et al. 2021; Pauli et al. 2021). The gene discussed is FBRSL1; the disease is microcephaly.
