Translational Reading Frame Predicts The Pathogenicity Of C-Terminal Frameshift Deletions In Mecp2, Jacky Guy, Elena Hein, Beatrice Alexander-Howden, Timur Von Bock Und Polach, Tricia Mathieson, Benjamin P Kleinstiver, Huda Y Zoghbi, Adrian Bird

Duncan NRI Faculty and Staff Publications

Mutations in the MECP2 gene cause the severe neurological disorder Rett syndrome. A cluster of frameshift-causing C-terminal deletions (CTDs) removes ~100 amino acids and accounts for approximately 10% of RTT-causing mutations. Their pathogenicity is unexpected because this C-terminal domain is dispensable in mice. Analysis of pathogenic and benign human MECP2 variants reveals that some individuals with apparently typical CTDs do not develop Rett syndrome, confirming that C-terminal truncations are not intrinsically pathogenic. Using human sequence data and mouse models we show that pathogenicity results from a marked reduction in MeCP2 levels and depends on the presence of a proline proline …

Fieldwork Educators' Perspectives On Occupational Therapy Students Addressing Sexuality And Intimacy: Expectations, Supports, And Barriers, Elizabeth Deluca-Berg

Student Dissertations

Sexuality and intimacy are recognized as meaningful occupations within occupational therapy practice; however, they remain inconsistently addressed in clinical care. Previous research has identified limited educational preparation as a contributing factor to occupational therapists' discomfort and lack of confidence in addressing these occupations. Although classroom instruction provides foundational knowledge, Level II fieldwork serves as the primary setting in which students apply knowledge within authentic clinical environments. Despite the central role of FW educators in facilitating students' professional development, little research has explored how they prepare OT students to address sexuality and intimacy during fieldwork. The purpose of this basic qualitative …
