Metabolic complications in myotonic dystrophy type 1: A cross-sectional survey using the National Registry of Japan.

J Neurol Sci 2021 May 27;427:117511. Epub 2021 May 27.

Department of Neurology, National Hospital Organization Aomori National Hospital, Namioka, Aomori 038-1331, Japan. Electronic address:

Myotonic dystrophy type 1 (DM1) is the most common form of muscular dystrophy in adults, affecting multiple organs, including the eyes, heart, endocrine system, and central nervous system. The broad spectrum of DM1 symptoms has been attributed to the aberrant pre-mRNA splicing of various genes due to an abnormal expansion of the CTG repeat in the 3' untranslated region of the DMPK gene. The current challenge in the clinical care of DM1 is the lack of well-established protocols for the management of each organ disorder or symptom. Read More

Diverse genetic causes of polymicrogyria with epilepsy.


Epilepsia 2021 Apr 5;62(4):973-983. Epub 2021 Apr 5.

Objective: We sought to identify novel genes and to establish the contribution of known genes in a large cohort of patients with nonsyndromic sporadic polymicrogyria and epilepsy.

Methods: We enrolled participants with polymicrogyria and their parents through the Epilepsy Phenome/Genome Project. We performed phenotyping and whole exome sequencing (WES), trio analysis, and gene-level collapsing analysis to identify de novo or inherited variants, including germline or mosaic (postzygotic) single nucleotide variants, small insertion-deletion (indel) variants, and copy number variants present in leukocyte-derived DNA.

Neonatal Screening in Europe Revisited: An ISNS Perspective on the Current State and Developments Since 2010.

Int J Neonatal Screen 2021 Mar 5;7(1). Epub 2021 Mar 5.

Norwegian National Unit for Newborn Screening, 0424 Oslo, Norway.

Neonatal screening (NBS) was initiated in Europe during the 1960s with the screening for phenylketonuria. The panel of screened disorders ("conditions") then gradually expanded, with a boost in the late 1990s with the introduction of tandem mass spectrometry (MS/MS), making it possible to screen for 40-50 conditions using a single blood spot. The most recent additions to screening programmes (screening for cystic fibrosis, severe combined immunodeficiency and spinal muscular atrophy) were assisted by or realised through the introduction of molecular technologies.

The sodium leak channel NALCN regulates cell excitability of pituitary endocrine cells.

FASEB J 2021 May;35(5):e21400

IGF, Université de Montpellier, CNRS, INSERM, Montpellier, France.

Anterior pituitary endocrine cells that release hormones such as growth hormone and prolactin are excitable and fire action potentials. In these cells, several studies previously showed that extracellular sodium (Na ) removal resulted in a negative shift of the resting membrane potential (RMP) and a subsequent inhibition of the spontaneous firing of action potentials, suggesting the contribution of a Na background conductance. Here, we show that the Na leak channel NALCN conducts a Ca - Gd -sensitive and TTX-resistant Na background conductance in the GH cell line, a cell model of pituitary endocrine cells. Read More

Predictive fat mass equations for spinal muscular atrophy type I children: Development and internal validation.

Clin Nutr 2021 Apr 26;40(4):1578-1587. Epub 2021 Feb 26.

Department of Endocrine and Metabolic Diseases, Obesity Unit and Laboratory of Nutrition and Obesity Research, IRCCS (Scientific Institute for Research, Hospitalization, and Healthcare) Italian Auxologic Institute (IAI), Milan, Italy; International Center for the Assessment of Nutritional Status (ICANS), Department of Food Environmental and Nutritional Sciences (DeFENS), University of Milan, Milan, Italy.

Background: Body composition assessment is paramount for spinal muscular atrophy type I (SMA I) patients, as weight and BMI have proven to be misleading for these patients. Despite its importance, no disease-specific field method is currently available, and the assessment of body composition of SMA I patients requires reference methods available only in specialized settings.

Objective: To develop predictive fat mass equations for SMA I children based on simple measurements, and compare existing equations to the new disease-specific equations. Read More

Endocrine myopathies: clinical and histopathological features of the major forms.

Acta Myol 2020 Sep 1;39(3):130-135. Epub 2020 Sep 1.

Department of Clinical and Experimental Medicine, University of Messina, Italy.

Endocrinopathies, such as thyroid and parathyroid diseases, disorders of the adrenal axis, and acromegaly are included among the many causes of myopathy. Muscle disturbances caused by endocrine disorders are mainly due to alterations in the protein and carbohydrate metabolisms. Either a deficiency or excess of hormones produced by the glands can cause muscle dysfunction that can be reversed by starting hormone replacement therapy or acting on hormone dysfunction. Read More
