Background: Late-onset Pompe disease (LOPD) is an autosomal recessive lysosomal storage disorder that results in severe progressive proximal muscle weakness. Over time, reductions in muscle strength result in respiratory failure and a loss of ambulation. Delayed diagnosis of LOPD deprives patients of treatments that can enhance quality of life and potentially slow disease progression.

Anderson-Fabry disease (AFD) is a X-linked lysosomal storage disorder that can result in cardiac dysfunction including left ventricular hypertrophy (LVH) and conduction abnormalities (Frontiers in cardiovascular medicine vol. 10) [1]. The manifestations of AFD in women may be isolated to one organ and occur late in life due to the random inactivation of the X chromosome.

Background: Monoclonal gammopathy (MG) has been reported in association with numerous neurological disorders but the spectrum of MG-associated myopathies remains poorly described.
Objective: To report a newly acquired myopathy associated with MG.
Methods: Three adult patients with the same phenotype from two French referral centers were prospectively analyzed.
GM2 gangliosidosis is lysosomal storage disorder caused by deficiency of the heterodimeric enzyme β-hexosaminidase A. Tay-Sachs disease is caused by variants in encoding the α-subunit and Sandhoff disease is caused by variants in encoding the β-subunit. Due to shared clinical and biochemical findings, the two have been considered indistinguishable.
