RYR1 causing distal myopathy
BACKGROUND Congenital myopathies due to ryanodine receptor (RYR1) mutations are increasingly identified and correlate with a wide range of phenotypes, most commonly that of malignant hyperthermia susceptibility and central cores on muscle biopsy with rare reports of distal muscle weakness, but in the setting of early onset global weakness. METHODS We report a case of a patient presenting with...
متن کاملClinical and Pathologic Findings of Korean Patients with RYR1-Related Congenital Myopathy
BACKGROUND AND PURPOSE This study was designed to investigate clinical and pathologic characteristics of five Korean patients with RYR1-related congenital myopathy (CM). METHODS Five patients from unrelated families were diagnosed with RYR1-related CM via direct or targeted sequencing of RYR1. Their clinical, mutational, and pathologic findings were then analyzed. RESULTS Seven different mu...

متن کاملExpanding the genetic spectrum of ANOS1 mutations in patients with congenital hypogonadotropic hypogonadism.
STUDY QUESTION What is the prevalence and functional consequence of ANOS1 (KAL1) mutations in a group of men with congenital hypogonadotropic hypogonadism (CHH)? SUMMARY ANSWER Three of forty-two (7.1%) patients presented ANOS1 mutations, including a novel splice site mutation leading to exon skipping and a novel contiguous gene deletion associated with ichthyosis. WHAT IS KNOWN ALREADY CHH...
متن کاملLipid raft disease? A new severe congenital myopathy.
We report a 5-year-old girl with a unique neuromuscular disorder manifested by early onset of the disease, delayed motor development, joint contractures, dysmorphy, cobbler's chest, generalized muscle hypoplasia and weakness. Morphological examination revealed muscle cell immaturity and the appearance of multilamellar myelin-like structures within and outside the sarcolemma. Overexpression of a...
