Mira Irons,Ellen R. Elias,Diane Abuelo,Marilyn J. Bull,Carol L. Greene,Virginia P. Johnson,Laura D Keppen,Carolyn Schanen,G. Stephen Tint,Gerald Salen +9 more
TL;DR: Biochemical improvement in sterol levels and in the ratio of cholesterol to total sterols was noted in all patients, and clinical improvement in growth and neurodevelopmental status was also observed.
Journal ArticleDOI
Functional, histopathologic and natural history study of neuropathy associated with EGR2 mutations
Kinga Szigeti,Wojciech Wiszniewski,Gulam Mustafa Saifi,Diane L. Sherman,Norbert Sule,Adekunle M. Adesina,Pedro Mancias,Sozos Ch. Papasozomenos,Geoffrey P. Miller,Laura D Keppen,Donna Daentl,Peter J. Brophy,James R. Lupski +12 more
TL;DR: It is confirmed that respiratory compromise and cranial nerve dysfunction are commonly associated with EGR2 mutations and can be useful in guiding molecular diagnosis.
Journal ArticleDOI
Marshall-Smith syndrome: natural history and evidence of an osteochondrodysplasia with connective tissue abnormalities.
Margaret P Adam,Raoul C.M. Hennekam,Laura D Keppen,Marilyn J. Bull,Carol L. Clericuzio,Leah W. Burke,Kelly E. Ormond,Eugene H. Hoyme +7 more
TL;DR: An increased rate of nontraumatic fractures and other bony and connective tissue abnormalities that support the hypothesis that MSS should be considered an osteochondrodysplasia are demonstrated.
Journal ArticleDOI
Variations in IBD (ACAD8) in children with elevated C4-carnitine detected by tandem mass spectrometry newborn screening.
Christina Bak Pedersen,Claus Bischoff,Ernst Christensen,Henrik Simonsen,Allan M. Lund,Sarah P. Young,Dwight D. Koeberl,David S. Millington,Charles R. Roe,Diane S. Roe,Ronald J.A. Wanders,Jos P.N. Ruiter,Laura D Keppen,Quinn Stein,Inga Knudsen,Niels Gregersen,Brage S. Andresen,Brage S. Andresen +17 more
TL;DR: Functional studies in isolated mitochondria demonstrated that the IBD variations present in the Danish newborn disturbed protein folding and reduced the levels of correctly folded IBD tetramers.
Journal ArticleDOI
Clinical phenotype and molecular analysis of a three-generation family with an interstitial deletion of the short arm of chromosome 5.
TL;DR: Molecular comparison of the deletion in this 3-generation family with an interstitial deletion of the short arm of chromosome 5 suggests that the clinical findings are due specifically to the chromosomal material deleted from 5p13.3.
