Corrigendum: Clinical Characteristics and Neurologic Outcomes of X-Linked Myotubular Myopathy

X-linked myotubular myopathy

X-linked myotubular myopathy (McKusick no. 31040) is a congenital myopathy in which affected male subjects typically present with severe hypotonia and respiratory distress at birth. Surviving patients have prolonged ventilator dependence and grossly delayed motor milestones but usually have intact intelligence.1-3 However, the long-term prognosis as reported in the literature is generally poor,...

X-linked myotubular myopathy and chylothorax.

X-linked myotubular myopathy usually presents at birth with hypotonia and respiratory distress. Phenotypic presentation, however, can be extreme variable. We report on a newborn baby, who presented with the severe form of the disease. In the second week of life, he developed a clinically relevant chylothorax, needing drainage and treatment with octreotide acetate. Pleural effusions are frequent...

X-inactivation patterns in carriers of X-linked myotubular myopathy.

X-linked myotubular myopathy is a rare severe muscle disorder in affected male neonates. Most female carriers are free from symptoms. Skewed X inactivation has been proposed to be responsible for the affected phenotype seen in some carriers. We have compared the X inactivation patterns in blood DNA with the clinical phenotype in carriers of X-linked myotubular myopathy. The X-inactivation analy...

[A case of X-linked myotubular myopathy with chylothorax].

We report a case of X-linked myotubular myopathy with chylothorax. A male infant weighing 2,114 g was born to a mother whose pregnancy was complicated with polyhydramnios from gestational week 32. At gestational week 37, emergent caesarian section was performed due to membrane rupture followed by fetal bradycardia. Ventilatory support was necessary because the neonate showed severe birth asphyx...
