This CNV encompasses 30 protein coding genes. Distal 8p deletions that vary in size and location within 8p23 have been reported in multiple individuals with features that include intellectual disability, developmental delay, motor impairment, behavioral differences, congenital heart defects, microcephaly, and mild facial dysmorphism (PMID: 1619636; 19344873; 29165669; 33925474).
