Chromosome 8p Syndromes Clinical Presentation and Management Guidelines

Rearrangements of the p-arm of Chromosome 8 can result in a spectrum of neurodevelopmental challenges, along with increased risk of epilepsy, structural brain and cardiac malformations, persisting developmental delays, and other health challenges. The majority of patients reported on in this sample are characterized by an inverted-duplication deletion rearrangement, but deletions, duplications, and mosaic ring changes in 8p result in similar phenotype. In this report, we add to the phenotypic and functional description of these patients according to their specific chromosomal rearrangement, share neuro-psychometric values, and propose surveillance care guidelines for caregivers and medical providers of patients with Chromosome 8p Syndromes. Observations from clinical experience with 24 patients seen at our 8p-dedicated Multi-Disciplinary Neurogenetics program are shared. In this report, we add to the phenotypic and functional description of patients with Chromosome 8p Syndrome through clinical observations with 24 patients seen at our 8p-dedicated Multi-Disciplinary Neurogenetics program. Novel to this population, we share neurodevelopmental and neuropsychological attainment according to their specific chromosomal rearrangements and propose surveillance care guidelines for caregivers and medical providers of patients with Chromosome 8p Syndromes.image
