Chromosome 8p Syndromes Clinical Presentation and Management Guidelines

Abstract

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.

The Project 8p Foundation (Project 8p) was created in 2018 to:

  • Accelerate future treatments, not only for 8p, but potentially for other chromosome-wide diseases as well.
  • Lead with knowledge from patients. Currently, there is no cure for 8p disorders, nor is there a standard course of treatment.

The Project 8p Foundation (Project 8p) was created in 2018 to:

  • Raise transformative funding for pioneering scientific research into treatments for a complex, rare disease involving 250+ affected genes on the short arm of the 8 th chromosome (8p). Rearrangements of these genes causes significant abnormalities to the entire neurological system, thus all organs and functions of the body– with variance in cognitive functions, gross motor skills, social development and other challenges during infancy, and throughout life;
  • Empower a unified community of 8p patients and their families so they can have meaningful lives today; and
  • Accelerate future treatments, not only for 8p, but potentially for other chromosome-wide diseases as well.
