    Corticobasal syndrome in a man with Gaucher disease type 1: Expansion of the understanding of the neurological spectrum.
    (Molecular Genetics and Metabolism Reports, 2018-12) Potnis, Kunal C; Flueckinger, Lauren B; DeArmey, Stephanie M; Alcalay, Roy N; Cooney, Jeffrey W; Kishnani, Priya S
    Gaucher disease (GD) is an autosomal recessive condition that results from a deficiency of the enzyme β-glucocerebrosidase. The increased risk of primary parkinsonism symptoms among individuals affected with GD and carriers for the disorder is well-documented in the literature. However, these risks and case reports often reflect patients with classical Parkinson's disease (PD) symptoms. We report a patient with GD type 1 who was diagnosed with corticobasal syndrome (CBS), a clinical atypical parkinsonism diagnosis, in his sixth decade of life. Our case highlights the need to consider forms of atypical parkinsonism such as CBS in addition to PD in the differential diagnosis of cognitive and motor changes in patients with GD type 1. We also recommend careful assessment and routine monitoring of cognition, mood, behavior, sleep patterns, olfaction, and memory in patients with GD type 1 to identify early symptoms indicative of neurological involvement.

    The emerging phenotype of long-term survivors with infantile Pompe disease.
    (Genetics in medicine : official journal of the American College of Medical Genetics, 2012-09) Prater, Sean N; Banugaria, Suhrad G; DeArmey, Stephanie M; Botha, Eleanor G; Stege, Erin M; Case, Laura E; Jones, Harrison N; Phornphutkul, Chanika; Wang, Raymond Y; Young, Sarah P; Kishnani, Priya S

    Purpose

    Enzyme replacement therapy with alglucosidase alfa for infantile Pompe disease has improved survival creating new management challenges. We describe an emerging phenotype in a retrospective review of long-term survivors.

    Methods

    Inclusion criteria included ventilator-free status and age ≤6 months at treatment initiation, and survival to age ≥5 years. Clinical outcome measures included invasive ventilator-free survival and parameters for cardiac, pulmonary, musculoskeletal, gross motor, and ambulatory status; growth; speech, hearing, and swallowing; and gastrointestinal and nutritional status.

    Results

    Eleven of 17 patients met study criteria. All were cross-reactive immunologic material-positive, alive, and invasive ventilator-free at most recent assessment, with a median age of 8.0 years (range: 5.4-12.0 years). All had marked improvements in cardiac parameters. Commonly present were gross motor weakness, motor speech deficits, sensorineural and/or conductive hearing loss, osteopenia, gastroesophageal reflux, and dysphagia with aspiration risk. Seven of 11 patients were independently ambulatory and four required the use of assistive ambulatory devices. All long-term survivors had low or undetectable anti-alglucosidase alfa antibody titers.

    Conclusion

    Long-term survivors exhibited sustained improvements in cardiac parameters and gross motor function. Residual muscle weakness, hearing loss, risk for arrhythmias, hypernasal speech, dysphagia with risk for aspiration, and osteopenia were commonly observed findings.
