Abstract
BACKGROUND AND PURPOSE Extension and characteristics of WM involvement other than the brain stem remain inadequately investigated in ARSACS. The aim of this study was to investigate whole-brain WM alterations in patients with ARSACS. MATERIALS AND METHODS Nine Turkish unrelated patients with ARSACS and 9 sex- and age-matched healthy control participants underwent neurologic examination, molecular studies, electrophysiologic studies, and DTI of the brain. TBSS was used for whole-brain voxelwise analysis of FA, AD, RD, mean diffusivity of WM. Tractographies for the CST and TPF were also computed. RESULTS Molecular studies revealed 8 novel mutations (3 nonsense, 4 missense, and 1 frameshift insertion) and a missense variation in the SACS gene. Thick TPF displaced and compressed the CST in the pons. The TPF had increased FA, decreased RD, and increased AD, which may be attributed to hypertrophy and/or hypermyelination. Widespread decreased FA and increased RD, suggesting demyelination, was found in the limbic, commissural, and projection fibers. In addition to demyelination, CST coursing cranial and caudal to the pons also showed a marked decrease in AD, suggesting axonal degeneration. Electrophysiologic studies revealed findings that concur with demyelination and axonal involvement. CONCLUSIONS In addition to developmental changes of the TPF and their effects on the CST in the brain stem, axonal degeneration mainly along the pyramidal tracts and widespread demyelination in WM also occur in patients with ARSACS. Widespread tissue damage may be associated with extensive loss of sacsin protein in the brain and may explain a wide range of progressive neurologic abnormalities in patients with ARSACS.

Abstract
Injury to the dentato-rubro-olivary pathway causes hypertrophy and enlargement of the inferior olivary nuclei, which is called hypertrophic olivary degeneration (HOD). To date, adult cases of HOD have usually been reported, and there are only a few individual paediatric cases with limited radiological emphasis in the literature. We present the clinical and MRI findings of four new paediatric cases with HOD. Three of the patients had a posterior fossa surgery, and one did not have an identifiable cause.

Abstract
D-2-hydroxyglutaric aciduria (D-2-HGA; OMIM 600721) is a rare autosomal recessive neurometabolic disorder with a wide clinical spectrum. The severe phenotype is homogeneous and is characterized by early infantile-onset epileptic encephalopathy with hypotonia, delayed cerebral visual development, cardiomyopathy and facial dysmorphic features. The mild phenotype has a more variable clinical expression with hypotonia and developmental delay. We present peripheral neuropathy as an additional clinical and electrophysiological feature in a 16-year-old boy with a homozygous missense mutation in exon 3 of the D-2-hydroxyglutarate dehydrogenase gene (D2HGDH) at position c.458T>C. This mutation results in replacement of a methionine residue, which was highly conserved during evolution, by threonine (p.Met153Thr).

Abstract
L-2-Hydroxyglutaric aciduria (L-2-HGA, MIM 236792) is a rare autosomal recessive neurodegenerative disorder characterized by psychomotor delay, cerebellar and extrapyramidal signs and subcortical leukoencephalopathy with basal ganglia and dentate nuclei involvement. Mutations in the gene L2HGDH ( C14ORF160/DURANIN/) have been identified as causative for L-2-HGA. A feature disproportionally associated with L-2-HGA is the development of malignant brain tumors. In our cohort of 40 patients with L-2-HGA, two developed medulloblastoma and glioblastoma multiforme during the course of the disease. Two missense mutations in two patients were identified in the L2HGDH gene in exon 3 (c.292C-->T) and in exon 7 (c.887T-->A). Both mutations were present in the homozygous state. Serial MR imaging findings as well as MR spectroscopy imaging is reported in a patient who developed glioblastoma multiforme.

Abstract
Dropped head syndrome is characterized by severe weakness of neck extensor muscles with sparing of the flexors. It is a prominent sign in several neuromuscular conditions, but it may also be an isolated feature with uncertain aetiology. We report two children in whom prominent weakness of neck extensor muscles is associated with mutations in lamin A/C (LMNA) and selenoprotein N1 (SEPN1) genes, respectively. This report expands the underlying causes of the dropped head syndrome which may be the presenting feature of a congenital muscular dystrophy.

Abstract
Muscle-eye-brain disease (MEB) is an autosomal recessive congenital muscular dystrophy with ocular abnormalities and type II lissencephaly. MEB is caused by mutations in the protein O-linked mannose beta1,2-N-acetylglucosaminyltransferase (POMGnT1) gene on chromosome 1q33. POMGnT1 is a glycosylation enzyme that participates in the synthesis of O-mannosyl glycan. The disease is characterized by altered glycosylation of alpha-dystroglycan. The clinical spectrum of MEB phenotype and POMGnT1 mutations are significantly expanded. We would like to present two cases with MEB disease with POMGnT1 mutations, whose clinical picture shows heterogeneity. The patient with R442H mutation had the classical form of the disease although the one with IVS17-2A-->G homozygous mutation had severe autistic features as the dominating presenting sign. These two cases represent different spectrums of one disorder. To the best of our knowledge, autistic features and stereotypical movements have not been included thus far as a part of broad and heterogeneous MEB spectrum.

Abstract
BACKGROUND Congenital muscular dystrophies (CMD) are autosomal recessive disorders that present within the first 6 months of life with hypotonia and a dystrophic muscle biopsy. CNS involvement is present in some forms. The fukutin-related protein gene (FKRP) is mutated in a severe form of CMD (MDC1C) and a milder limb girdle dystrophy (LGMD2I). Both forms have secondary deficiencies of laminin alpha2 and alpha-dystroglycan immunostaining. Structural brain involvement has not been observed in patients with FKRP gene mutations. METHODS The authors studied two unrelated patients who had a pattern of muscle involvement identical to MDC1C, mental retardation, and cerebellar cysts on cranial MRI. The FKRP gene was analyzed along with the skeletal muscle expression of laminin alpha2 and alpha-dystroglycan. RESULTS The muscle biopsy of both patients showed severe dystrophic findings, a reduction in laminin alpha2, and profound depletion of alpha-dystroglycan. Both patients had homozygous FKRP gene mutations not previously reported (C663A [Ser221Arg] and C981A [Pro315Thr]). CONCLUSIONS Mutations within the FKRP gene can result in CMD associated with mental retardation and cerebellar cysts. This adds structural brain defects to the already wide spectrum of abnormalities caused by FKRP mutations. The severe depletion of alpha-dystroglycan expression suggests that FKRP is involved in the processing of alpha-dystroglycan.

Abstract
Spinal muscular atrophy (SMA) is a clinically and genetically heterogeneous disease characterised by loss of motor function and muscle atrophy due to anterior horn cell degeneration. The most common variant is chromosome 5-linked proximal SMA, ranging in severity from congenital onset and infantile death to onset in adult life. Genetically separate variants with different distribution of weakness and/or additional features such as central nervous system involvement have been described. A rare variant with associated myoclonic epilepsy and lower motor neuron disease had been previously described in three families before the SMN gene, responsible for the common form of SMA, was isolated. We report four patients from two additional families affected by a syndrome characterised by severe and progressive myoclonic epilepsy and proximal weakness, tremor and lower motor neuron disease proven by electrophysiologic and muscle biopsy findings. Extensive metabolic investigations were normal and genetic analysis excluded the SMN gene. This study confirms that the association of myoclonic epilepsy and motor neuron disease represents a separate clinical and genetic entity from chromosome 5-linked SMA, the primary defect of which remains unknown.

Abstract
D-Glyceric aciduria is a disease with a very heterogeneous group of symptoms, with D-glyceric acid excretion as the chief common characteristic. Findings described in previous patients include progressive neurological impairment, hypotonia, seizures, failure to thrive and metabolic acidosis. However, there are also asymptomatic patients with mild neurological impairment. A six-month-old boy was admitted to our clinic with the complaints of dullness to his environment, seizures and autistic behaviour. EEG revealed multifocal generalized epileptic activity in a hypsarrhythmia pattern. Organic acid analysis (GC-MS) in urine revealed increased glyceric acid excretion. Analysis of the optical form of glyceric acid by a polarimetric method supported the diagnosis of D-glyceric aciduria. MRI showed white matter lesions with cerebral atrophy, particularly in the frontotemporal regions, and reversible abnormalities in the mesencephalon, thalami and globus pallidium resolving after fructose restriction in the diet. To our knowledge, this is the first case report of a patient with D-glyceric aciduria who presented with West syndrome and autistic behaviour in whom serial MRI findings are also defined.

Abstract
We report three infants with the diagnosis of molybdenum cofactor deficiency. The key findings leading to diagnosis were neonatal seizures unresponsive to treatment, craniofacial dysmorphic features, hyperexcitability, low blood uric acid levels, and neuroimaging findings. The parents were consanguineous in two of these patients. The diagnosis was established by the presence of low blood uric acid levels, positive urine sulfite reaction, quantitative aminoacid analysis, and high-voltage electrophoresis of the urine sample showing a typical increase of S-sulfo-L-cysteine. Skin fibroblast cultures confirmed the diagnosis. Magnetic resonance imaging findings were suggestive of encephalomalacia with cystic changes due to hypoxic-ischemic encephalopathy. We conclude that molybdenum cofactor deficiency must be included in the differential diagnosis of patients presenting with intractable seizures in the newborn period who have computed tomography and magnetic resonance imaging findings reminiscent of those of hypoxic-ischemic encephalopathy, and the urine sulfite dipstick test can be a part of the evaluation of these infants in neonatal intensive care units.
