Bilateral frontoparietal polymicrogyria (BFPP) is an abnormality of the developing brain in which the brain develops too many folds (which are also unusually small). BFPP specifically affects the frontal and parietal lobes and occurs in both sides of the brain (bilateral). Signs and symptoms of BFPP typically include moderate to severe intellectual disability, motor developmental delay, seizures, cerebellar ataxia, strabismus, dysconjugate gaze (eyes that are not aligned) and other findings. Some cases of BFPP are caused by mutations in the GPR56 gene, and it is inherited in an autosomal recessive manner.[1]
