Ogden Syndrome
Ogden Syndrome, also known as n-terminal acetyltransferase deficiency (NATD), is an x-linked disorder of infancy comprising a distinct combination of distinctive craniofacial features producing an aged appearance, growth failure, hypotonia, global developmental delays, cryptorchidism, and acquired cardiac arrhythmias. The first family was identified in Ogden, Utah, with five affected boys in two generations of family members. A mutation was identified as a c.109T>C (p.Ser37Pro) variant in (NAA10 ), a gene encoding the protein Naa10 catalytic subunit of the major human N-terminal acetyltransferase (NatA). This same mutation was identified in a second unrelated family, with three affected boys in two generations. This X-linked Malformation and Infantile Lethality Syndrome has provisionally been named Ogden Syndrome, in honor of the hometown where the first family resides.
== History ==
Halena Black had her first son, Kenny Rae, in 1979. Being that he was her first born child, Black did not notice that something was wrong. Kenny Rae Black passed in 1980, right before his first birthday and was the first know infant to die from Ogden Syndrome. However, it did not end there. Halena Black continued to have children and in 1987 she had her next boy, Hyrum. From the start, Black noticed that Hyrum had the same characteristics as Kenny Rae but thought it was due to the fact that they were brothers. It did not cross her mind that they could share the same underlying disease. Like Kenny Rae, Hyrum passed before his first birthday. It was only until Black's daughters began having children of their own that she realized something was not right. The sons born to Black's daughters looked identical to her own sons and that was when Halena sought medical help.〔 Answers came thirty years after Kenny Rae's 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 shockingly similar characteristics. Lyon tested the new family and found they shared the same rare mutation as the Black family.The existence of another family made this mutation a syndrome, and not something isolated to the Blacks.
