The boys were never able to sit up on their own, and none learned how to talk. They all had a characteristically aged appearance, earning them the family nickname of "little old men." Several of the boys had structural anomalies of their hearts including ventricular septal defect, atrial septal defect, and pulmonary artery stenosis. Events recorded on electrocardiogram before death included torsades de pointes, premature ventricular contraction (PVC), premature atrial contraction (PAC), supraventricular tachycardia (SVtach), and ventricular tachycardia (Vtach). Most of the children had inguinal hernias, and the majority had, at least, unilateral cryptorchidism. All had neonatal hypotonia progressing to hypertonia, and cerebral atrophy on MRI; several, but not all, had neurogenic scoliosis. Death occurred prior to two years in all cases and prior to one year in the majority. There are extensive clinical details for each child reported in the original publication

Biochemistry
Ogden syndrome is a lethal X-linked recessive condition. Because the affected gene is on the X-chromosome, it affects males far more severely due to the fact that males only carry one copy of the X chromosome so the mutation is in every cell but females carry two and therefore some cells may use the non mutated copy and others use the mutated copy. It was the first reported human genetic disorder linked with a mutation in an N-terminal acetyltransferase (NAT) gene. The original Ogden family males have the Ser37Pro (S37P) mutation in the gene encoding NAA10, the catalytic subunit of NatA, the major human enzyme heterodimer involved in the post-translational acetylation of proteins.
The sons born to Blacks daughters looked identical to her own sons and that was when Halena sought medical help.Answers came thirty years after Kenny Raes death. Ogden syndrome was discovered in 2011 by a team of researchers led by Gholson J. Lyon, consisting of: Alan F. Rope, Kai Wang, Rune Evjenth, Jinchuan Xing, Jennifer J. Johnston, Jeffrey J. Swensen, W. Evan Johnson, Barry Moore, Chad D. Huff, Lynne M. Bird, John C. Carey, John M. Opitz, Cathy A. Stevens, Tao Jiang, Christa Schank, Heidi Deborah Fain, Reid J. Robison, and 10 others. Just before Lyon was about to publish his findings, another team researching a family living mainly in California contacted him. The newly found family had also lost three infant boys all with similar characteristics. This new family shared the same rare mutation as the Black family. The existence of another family made this mutation a syndrome, and not something isolated. References
