Summaries for Polymicrogyria, Bilateral Frontoparietal

NIH Rare Diseases : 50 bilateral frontoparietal polymicrogyria (bfpp) is a rare neurological disorder that affects the cerebral cortex (the outer surface of the brain). bfpp specifically affects the frontal and parietal lobes on both sides of the brain (bilateral). signs and symptoms typically include moderate to severe intellectual disability, developmental delay, seizures, cerebellar ataxia, strabismus, and dysconjugate gaze (eyes that are not aligned). some cases are caused by mutations in the gpr56 gene and are inherited in an autosomal recessive manner. treatment is based on the signs and symptoms present in each person. last updated: 6/8/2015

MalaCards based summary : Polymicrogyria, Bilateral Frontoparietal, also known as bilateral frontoparietal polymicrogyria, is related to polymicrogyria, symmetric or asymmetric and polymicrogyria, and has symptoms including seizures, nystagmus and intellectual disability. An important gene associated with Polymicrogyria, Bilateral Frontoparietal is ADGRG1 (Adhesion G Protein-Coupled Receptor G1). Affiliated tissues include brain, cortex and eye.

UniProtKB/Swiss-Prot : 66 Polymicrogyria, bilateral frontoparietal: A malformation of the cortex in which the brain surface is irregular and characterized by an excessive number of small gyri with abnormal lamination, most severe in the frontoparietal regions. BFPP clinical manifestations include developmental and psychomotor delay, cerebellar and pyramidal signs, truncal ataxia, seizures, hyperreflexia. Polymicrogyria is a heterogeneous disorder, considered to be the result of postmigratory abnormal cortical organization.
