Los Centros Carter para la Investigación del Cerebro, la Holoprosencefalia y Malformaciones Afines (The Carter Centers for Brain Research in Holoprosencephaly and Related Malformations) es una iniciativa conjunta de centros auspiciados de excelencia en el campo de la holoprosencefalia y tiene información sobre holoprosencefalia y sus causas. She had semilobar holoprosencephaly with developmental delay, abnormal facial features, intermittent seizures that were well controlled with medication, nasogastric tube for supplemental feedings, constipation, various endocrinology issues, and was wheelchair bound.
