Language and Cognitive Features in a Girl with Bosch-Boonstra-Schaaf Optic Atrophy Syndrome

Bosch-Boonstra-Schaaf optic atrophy syndrome (BBSOAS) is an extremely rare neurological condition caused by a disruption in the NR2F-1 gene. The most common clinical features are optic atrophy and intellectual and developmental delay. This case report aims to describe the cognitive and language profile of a six-year-old girl diagnosed with BBSOAS, with a focus on the syndrome's impact on her developmental outcomes. A detailed assessment of her cognitive and speech-language abilities is provided. Given the limited number of published case studies on BBSOAS, this report integrates relevant findings from the literature, including information on epidemiology, diagnostics, clinical manifestations, and developmental outcomes. It contributes to the expansion of the known mutational spectrum of BBSOAS, in addition to documenting its phenotypic presentation of cognitive and speech-language development. The case is analyzed within the context of current evidence, emphasizing the importance of early assessment, individualized intervention, ongoing developmental monitoring, and the potential for tailored support to promote optimal developmental outcomes.
