Terminal deletions of 8p have been reported in patients with variable phenotypes (Burnside RD, et al., Am J Med Genet A. 2013 Apr;161A(4):822-8. PMID: 23495222; de Vries, et al., Am J Med Genet. 2001 Apr 1;99(4):314-9. PMID: 11251999). This deletion is consistent with 8p23.1 microdeletion syndrome (Arghir et al., Clin Case Rep. 2020 Nov 12;9(1):314-321. PMID: 33505690, Cosemans et al., Neurogenetics. 2021 Jul;22(3):207-213. PMID: 33683518, Kessi et al., Front Neurol. 2018 Nov 19;9:947. PMID: 30510536). Haploinsufficiency of GATA4 is associated with autosomal dominant atrial septal defect-2 (OMIM 607941, Wat, et al., Am J Med Genet A. 2009 Aug;149A(8):1661-77. PMID: 19606479. Shimokawa, et al., Am J Med Genet A. 2005;136;49-51. PMID: 15937941). Thus, this copy number variant (CNV) is classified as pathogenic. (less)
