    Psychological distress in response to physical activity restrictions in patients with non-syndromic thoracic aortic aneurysm/dissection

    Individuals diagnosed with thoracic aortic aneurysm/dissection (TAAD) are given activity restrictions in an attempt to mitigate serious health complications and sudden death. The psychological distress resulting from activity restrictions has been established for other diseases or patient populations; however, individuals with non-syndromic TAAD have not been previously evaluated. Seventy-nine participants completed a questionnaire utilizing the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder (GAD-7) questionnaires, which assess levels of depression and anxiety respectively. Additionally, quantitative and qualitative questions explored self-reported psychological distress in response to activity restrictions. Individuals who reported higher PHQ + GAD scores had been living with a diagnosis longer than two years (p = 0.0004), were between 35 and 65 years old (p = 0.05), reported not coping well (p = 0.0035), and reported physical activity was "very important" (p = 0.04). Results from individual questions showed that individuals who reported their diagnosis affected them financially were 3.5 times more likely to report "feeling nervous, anxious, or on edge" (CI = [0.81, 15.6], p = 0.094). Qualitative analysis revealed themes that identified participant beliefs regarding distress, ability to cope, hindrances to coping ability, and resources. These results show psychological distress can result from physical activity restrictions in non-syndromic TAAD individuals. Additionally, certain subpopulations may be more susceptible to distress. This is the first study to examine the psychological distress individuals with non-syndromic TAAD experience as a result of prescribed activity restrictions. Genetic counselors and other healthcare professionals can utilize this information to provide more tailored cardiovascular genetic counseling and increase its therapeutic potential for patients.

    An unusual cause for Coffin–Lowry syndrome: Three brothers with a novel microduplication in RPS6KA3
    (Wiley, 2019-12) Castelluccio, Valerie J.; Vetrina, Francesco; Lynnes, Ty; Jones, Julie; Holloway, Lynda; Belonis, Alyce; Breman, Amy M.; Graham, Brett H.; Sapp, Katherine; Wilson, Theodore; Schwartz, Charles; Pratt, Victoria M.; Weaver, David D.; Medical and Molecular Genetics, School of Medicine
    Coffin–Lowry syndrome (CLS) is a rare X‐linked disorder characterized by moderate to severe intellectual disability, hypotonia, craniofacial features, tapering digits, short stature, and skeletal deformities. Using whole exome sequencing and high‐resolution targeted comparative genomic hybridization array analysis, we identified a novel microduplication encompassing exons five through nine of RPS6KA3 in three full brothers. Each brother presented with intellectual disability and clinical and radiographic features consistent with CLS. qRT‐PCR analyses performed on mRNA from the peripheral blood of the three siblings revealed a marked reduction of RPS6KA3 levels suggesting a loss‐of‐function mechanism. PCR analysis of the patients’ cDNA detected a band greater than expected for an exon 4–10 amplicon, suggesting this was likely a direct duplication that lies between exons 4 through 10, which was later confirmed by Sanger sequencing. This microduplication is only the third intragenic duplication of RPS6KA3, and the second and smallest reported to date thought to cause CLS. Our study further supports the clinical utility of methods such as next‐generation sequencing and high‐resolution genomic arrays to detect small intragenic duplications. These methods, coupled with expression studies and cDNA structural analysis have the capacity to confirm the diagnosis of CLS in these rare cases.
