Identification of a novel heterozygous DYSF variant in a large family with a dominantly-inherited dysferlinopathy.

Aims: Dysferlinopathy is an autosomal recessive muscular dystrophy, caused by bi-allelic variants in the gene encoding dysferlin (DYSF). Onset typically occurs in the second to third decade and is characterised by slowly progressive skeletal muscle weakness and atrophy of the proximal and/or distal muscles of the four limbs. There are rare cases of symptomatic DYSF variant carriers.

Liver Resection After Selective Internal Radiation Therapy with Yttrium-90: Safety and Outcomes.

Introduction: Selective internal radiotherapy (SIRT) with yttrium-90 (Y-90) is an intra-arterial therapy for hepatic malignancy in patients who are unsuitable for surgical resection. This treatment is considered palliative, although some patients can demonstrate a response that is adequate to facilitate surgical resection with curative intent.

Methods: All patients who underwent liver resection post SIRT were reviewed.

Leigh syndrome caused by mutations in is associated with a better prognosis.

Objectives: Mitochondrial methionyl-tRNA formyltransferase (MTFMT) is required for the initiation of translation and elongation of mitochondrial protein synthesis Pathogenic variants in have been associated with Leigh syndrome (LS) and mitochondrial multiple respiratory chain deficiencies. We sought to elucidate the spectrum of clinical, neuroradiological and molecular genetic findings of patients with bi-allelic pathogenic variants in .

Methods: Retrospective cohort study combining new cases and previously published cases.

Dissecting the neuronal vulnerability underpinning Alpers' syndrome: a clinical and neuropathological study.

Alpers' syndrome is an early-onset neurodegenerative disorder often caused by biallelic pathogenic variants in the gene encoding the catalytic subunit of polymerase-gamma (POLG) which is essential for mitochondrial DNA (mtDNA) replication. Alpers' syndrome is characterized by intractable epilepsy, developmental regression and liver failure which typically affects children aged 6 months-3 years. Although later onset variants are now recognized, they differ in that they are primarily an epileptic encephalopathy with ataxia.
