XXIV. SCF LAYMAN’S SUMMARY
DiGeorge syndrome is a genetic disorder caused by deletion of a small region of chromosome 22 known as 22q11.2. The deletion disrupts development of structures derived from the embryonic pharyngeal arches, resulting in immune deficiency, congenital heart disease, low calcium levels, developmental delays, and increased risk of psychiatric disorders. SCF interprets DiGeorge syndrome as a systems-level developmental communication disorder involving chromosomal haploinsufficiency, thymic dysfunction, cardiac morphogenic instability, endocrine dysregulation, and collapse of synchronized developmental regulatory systems.
