Abstract
Intellectual disability (ID) is a complex and phenotypically heterogeneous neurodevelopmental disorder characterized by significant deficits in cognitive and adaptive skills, debuting during the developmental period. In the last decade, microarray-based copy number variation (CNV) analysis has been proved as a strategy particularly useful in the discovery of loci and candidate genes associated with these phenotypes and is widely used in the clinics with a diagnostic purpose. In this study, we evaluated the usefulness of two genome-wide high density SNP microarrays -Cytogenetics Whole-Genome 2.7M SNP array (n=126 patients; Group 1) and CytoScan High-Density SNP array (n=447 patients; Group 2)- in the detection of clinically relevant CNVs in a cohort of ID patients from Galicia (NW Spain). In 159 (27.7%) patients, we detected 186 rare exonic chromosomal imbalances, that were grouped into the following classes: Clinically relevant (67/186; 36.0%), of unknown clinical significance (93/186; 50.0%) and benign (26/186; 14.0%). The 67 pathogenic CNVs were identified in 64 patients, which means an overall diagnostic yield of 11.2%. Overall, we confirmed that ID is a genetically heterogeneous condition and emphasized the importance of using genome-wide high density SNP microarrays in the detection of its genetic causes. Additionally, we provided clinical and molecular data of patients with pathogenic or likely pathogenic CNVs and discussed the potential implication in neurodevelopmental disorders of genes located within these variants.

Abstract
Monocarboxylate transporter 8 (MCT8) is an active and specific thyroid hormone transporter into neurons. MCT8 mutations cause an X-linked condition known as Allan-Herndon-Dudley syndrome and are characterized by impaired psychomotor development and typical abnormal thyroid function. We describe a 10-year-old boy with severe cognitive disability, axial hypotonia, spastic quadriplegia and sporadic dyskinetic episodes. He initially presented with thyroid dysfunction (high FT3, low rT3, low FT4 and normal TSH) and generalized retardation of the cerebral and cerebellar myelination in brain magnetic resonance imaging. The clinical and laboratory findings led to sequencing of the SLC16A2/MCT8 gene, which identified a novel missense mutation in exon 5. The study of peripheral markers of thyroid function suggests a paradoxical state of thyrotoxicosis in some peripheral tissues. Our patient had a typical clinical presentation at birth but because of the rarity of his disease his diagnosis was not made until the age of 7. The delay can also be explained by the omission of the free T3 assay in the first thyroid evaluation performed. This case therefore highlights the possible benefit of including the T3 assay in the study of patients with severe psychomotor disability of unknown etiology, thus eliminating extra costs for unnecessary complementary diagnostic tests.

Abstract
INTRODUCTION The vagus nerve stimulator is a therapeutic alternative in patients with epilepsy which is refractory to treatment with antiepileptic drugs that are not candidates for surgical resection. AIM To analyse the effectiveness of vagus nerve stimulator in the paediatric patients of our centre. PATIENTS AND METHODS Set of 13 patients implanted between 2008 y 2013. It was registered the frequency of crises prior to implantation, after a year and at the end of the monitoring period. As well, it was recorded the number of antiepileptic drugs used and in a qualitative way the behavioural improvement and the change in the intensity of the crises, besides the apparition of secondary effects and the removal or not of the device. RESULTS After a year, two years and at the end of the monitoring period it has been a fall in the number of crises about of 61%, 66.7% y 69% respectively, finding one patient free of crises after two years. At the end of the monitoring period, the 23% of those who had reduced their crises had experimented a reduction over 90%. Independently the effect on the number of crises, 77% of the patients presented an improvement in the intensity and the length of the crises, the same average showed a behavioural improvement. The secondary effects appeared in a 30.7% of the patients, being of mild intensity. CONCLUSIONS Despite the small size of our sample, our results shows that the vagus nerve stimulator has a relevant efficacy over the pediatric drug resistant population, as much in the frequency and intensity of the crises, as over the behaviour.

Abstract
Choline kinase beta gene (CHKB) mutations have been identified in Megaconial Congenital Muscular Dystrophy (MDCMC) patients, a very rare inborn error of metabolism with 21 cases reported worldwide. We report the case of a Spanish boy of Caucasian origin who presented a generalized congenital muscular hypotonia, more intense at lower limb muscles, mildly elevated creatine kinase (CK), serum aspartate transaminase (AST) and lactate. Electromyography (EMG) showed neurogenic potentials in the proximal muscles. Histological studies of a muscle biopsy showed neurogenic atrophy with enlarged mitochondria in the periphery of the fibers, and complex I deficiency. Finally, genetic analysis showed the presence of a homozygous mutation in the gene for choline kinase beta (CHKB: NM_005198.4:c.810T>A, p.Tyr270(∗)). We describe here the second Spanish patient whit mutation in CHKB gene, who despite having the same mutation, presented an atypical aspect: congenital neurogenic muscular atrophy progressing to a combined neuropathic and myopathic phenotype (mixed pattern).

Abstract
INTRODUCTION The 3q29 microdeletion and microduplication syndromes are characterised by a marked phenotypic heterogeneity, and delayed development and a mild-moderate degree of intellectual disability are the most frequent clinical manifestations. CASE REPORTS Two patients with reciprocal chromosomal aberrations in the 3q29 region. The patient with 3q29 microdeletion presented learning disabilities, borderline microcephaly, mild facial dysmorphism, attentional deficit and impulsiveness, and anxious and obsessive traits. The patient with reciprocal 3q29 microduplication presented learning disabilities, mild facial dysmorphism and a disruptive behavioural profile that was not previously associated with this duplication. CONCLUSIONS The phenotypes of these patients are compared and the literature about paediatric patients with 3q29 microdeletions and microduplications is reviewed.

Abstract
The few proximal 4q chromosomal aberrations identified in patients with neurodevelopmental phenotypes that have been published to date are variable in type, size and breakpoints and, therefore, encompass different chromosome bands and genes, making the establishment of genotype-phenotype correlations a challenging task. Here, microarray-based copy number analysis allowed us the detection of two novel and partially overlapping deletions in two unrelated families. In Family 1, a 4q13.1-q13.2 deletion of 3.84 Mb was identified in a mother with mild intellectual disability and in her two children, both with mild intellectual disability and attention deficit hyperactivity disorder. In Family 2, a de novo 4q13.2-q13.3 deletion of 6.81 Mb was detected in a female patient, born to unaffected parents, with a diagnosis of mild intellectual disability, behavioral disorder and facial dysmorphism. The shortest region of overlap between these two aberrations is located at chromosome 4q13.2 and includes 17 genes amongst of which we suggest UBA6 (ubiquitin-like modifier-activating enzyme 6) as a strong candidate gene for these phenotypes.

Abstract
The 8q21.11 microdeletion syndrome (OMIM # 614230) has been recently described and is primarily characterized by intellectual disability and facial dysmorphism. We describe here a male patient of 9 years 9 months of age with moderate intellectual disability and dysmorphic facial features. A high resolution copy number variation analysis, performed with the Affymetrix Cytogenetics Whole-Genome 2.7 M SNP array, allowed the identification of a heterozygous 7.069 Mb microdeletion at chromosome 8q21.11-q21.13. Clinical comparison of our patient with literature shows many similarities. However, the whole facial appearance of our patient, especially the elongated rather than rounded face and the absence of a wide nasal bridge and epicanthal folds, confers him a phenotype similar only to a subset, but not to the majority, of the hitherto described patients.

Abstract
Aicardi-Goutières syndrome is an inflammatory disease occurring due to mutations in any of TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR or IFIH1. We report on 374 patients from 299 families with mutations in these seven genes. Most patients conformed to one of two fairly stereotyped clinical profiles; either exhibiting an in utero disease-onset (74 patients; 22.8% of all patients where data were available), or a post-natal presentation, usually within the first year of life (223 patients; 68.6%), characterized by a sub-acute encephalopathy and a loss of previously acquired skills. Other clinically distinct phenotypes were also observed; particularly, bilateral striatal necrosis (13 patients; 3.6%) and non-syndromic spastic paraparesis (12 patients; 3.4%). We recorded 69 deaths (19.3% of patients with follow-up data). Of 285 patients for whom data were available, 210 (73.7%) were profoundly disabled, with no useful motor, speech and intellectual function. Chilblains, glaucoma, hypothyroidism, cardiomyopathy, intracerebral vasculitis, peripheral neuropathy, bowel inflammation and systemic lupus erythematosus were seen frequently enough to be confirmed as real associations with the Aicardi-Goutieres syndrome phenotype. We observed a robust relationship between mutations in all seven genes with increased type I interferon activity in cerebrospinal fluid and serum, and the increased expression of interferon-stimulated gene transcripts in peripheral blood. We recorded a positive correlation between the level of cerebrospinal fluid interferon activity assayed within one year of disease presentation and the degree of subsequent disability. Interferon-stimulated gene transcripts remained high in most patients, indicating an ongoing disease process. On the basis of substantial morbidity and mortality, our data highlight the urgent need to define coherent treatment strategies for the phenotypes associated with mutations in the Aicardi-Goutières syndrome-related genes. Our findings also make it clear that a window of therapeutic opportunity exists relevant to the majority of affected patients and indicate that the assessment of type I interferon activity might serve as a useful biomarker in future clinical trials.

Abstract
BACKGROUND Choline kinase beta gene (CHKB) mutations have been identified in Megaconial Congenital Muscular Dystrophy (MDCMC) patients, but never in patients with an additional combined deficiency of complexes I, III and IV and mitochondrial DNA (mtDNA) depletion. AIMS To report mutations in carry genes for MDCMC with respiratory chain defects and mtDNA depletion. METHODS Whole-exome sequencing (WES) was used to identify the carry genes in a Spanish child with muscle weakness, mild hypotonia at lower limb muscles, mildly elevated creatine kinase (CK), enlarged mitochondria in the periphery of the fibers, combined deficiency of complex I, III and IV and depletion of mtDNA. RESULTS With WES data, it was possible to get the whole mtDNA sequencing and discard any pathogenic variant in this genome. The first filter of WES data with the nuclear-encoded mitochondrial genes (MitoCarta) did not get any candidate. However, the analysis of whole exome uncovered a homozygous nonsense pathogenic mutation in CHKB gene (NM_005198.4:c.810T>A, p.Tyr270*). CONCLUSIONS Our data confirm the role of CHKB in MDCMC and point to this gene as unique candidate for the combined deficiency of respiratory chain and mtDNA depletion observed in this patient.

Abstract
BACKGROUND With over 50 different disorders and a combined incidence of up to 1/3000 births, lysosomal storage diseases (LSDs) constitute a major public health problem and place an enormous burden on affected individuals and their families. Many factors make LSD diagnosis difficult, including phenotype and penetrance variability, shared signs and symptoms, and problems inherent to biochemical diagnosis. Developing a powerful diagnostic tool could mitigate the protracted diagnostic process for these families, lead to better outcomes for current and proposed therapies, and provide the basis for more appropriate genetic counseling. METHODS We have designed a targeted resequencing assay for the simultaneous testing of 57 lysosomal genes, using in-solution capture as the enrichment method and two different sequencing platforms. A total of 84 patients with high to moderate-or low suspicion index for LSD were enrolled in different centers in Spain and Portugal, including 18 positive controls. RESULTS We correctly diagnosed 18 positive blinded controls, provided genetic diagnosis to 25 potential LSD patients, and ended with 18 diagnostic odysseys. CONCLUSION We report the assessment of a next-generation-sequencing-based approach as an accessory tool in the diagnosis of LSDs, a group of disorders which have overlapping clinical profiles and genetic heterogeneity. We have also identified and quantified the strengths and limitations of next generation sequencing (NGS) technology applied to diagnosis.

Abstract
Patients with Glutaric aciduria type 1 (GA-1) can be identified by newborn screening using tandem mass spectrometry. The clinical evolution of screened patients seems to be more favourable compared with those diagnosed later, although long-term evolution is still doubtful. We have evaluated the outcome in nine GA-1 patients diagnosed in our region during 12 years. Six were detected by newborn screening and 3 clinically. The birth prevalence was 1:35,027. High blood C5DC concentration, in 8/9 patients, was found, whereas all patients exhibited high concentration of this metabolite in urine. Therefore, urine C5DC was a good marker for the detection of this disease. Eight different mutations in the GCDH gene were identified, four of them were novel (p.R88H, p.Y398C, p.R372K, p.D220N); being p.R227P the mostcommon. Macrocephaly with enlarged frontotemporal subarachnoid space was present in 4/6 patients diagnosed by newborn screening, all these patients required high energy intake, and in two cases, enteral feeding during the first year of life was needed. One child had an intercurrent episode of feeding refuse with hypoglycemia at two years of age. The mean follow-up time of screened patients was 56 months, and patients still remain asymptomatic. However, after a mean follow-up of 97 months treatment efficacy was poor in unscreened patients, two of them showing a severe spastic tetraparesis. Plasma levels of lysine, tryptophan and carnitine, were the most useful biomarkers for the follow-up. Our data support that, early diagnosis and treatment strategies are essential measures for the good clinical evolution of GA-1 patients.

Abstract
We determined the serum concentration of biotin, zinc, antiepileptic drugs, and biotinidase enzyme activity in 20 children treated with valproic acid, in 10 children treated with carbamazepine, and in 75 age- and sex-matched healthy controls. There were no significant differences in the serum levels of biotin, and biotinidase enzyme activity between the patients treated with valproic acid, the patients treated with carbamazepine, and the control group. Zinc serum levels were lower in the patients treated with valproic acid and with carbamazepine than in the control group, but within the normal range. Hair loss was observed in 3 patients treated with valproic acid, with normal serum levels of biotin, zinc, and biotinidase activity, and the alopecia disappeared with the oral administration of biotin (10 mg/d) in 3 months. These results suggest that the treatment with valproic acid does not alter the serum levels of biotin, zinc, and biotinidase enzyme activity.

Abstract
The spectrum of the adenosine monophosphate (AMP) deaminase deficiency ranges from asymptomatic carriers to patients who manifest exercise-induced muscle pain, occasionally rhabdomyolysis, and idiopathic hyperCKemia. However, previous to the introduction of molecular techniques, rare cases with congenital weakness and hypotonia have also been reported. We report a 6-month-old girl with the association of congenital muscle weakness and hypotonia, muscle deficiency of adenosine monophosphate deaminase, and the homozygous C to T mutation at nucleotide 34 of the adenosine monophosphate deaminase-1 gene. This observation indicates the possible existence of a primary adenosine monophosphate deaminase deficiency manifested by congenital muscle weakness and hypotonia.

Abstract
Background There are several known autosomal genes responsible for
Ras/MAPK pathway syndromes, including
Noonan syndrome (NS) and related disorders (such as LEOPARD,
neurofibromatosis type 1), although mutations of these genes do not explain
all cases. Due to the important role played by the mitochondrion in the
energetic metabolism of cardiac muscle, it was recently proposed that
variation in the mitochondrial DNA (mtDNA) genome could be a risk factor in
the Noonan phenotype and in hypertrophic cardiomyopathy (HCM), which is a
common clinical feature in Ras/MAPK pathway syndromes. In order to test
these hypotheses, we sequenced entire mtDNA genomes in the largest series of
patients suffering from Ras/MAPK pathway
syndromes analyzed to date (n = 45),
most of them classified as NS patients
(n = 42). Methods/Principal Findings The results indicate that the observed mtDNA lineages were mostly of European
ancestry, reproducing in a nutshell the expected haplogroup (hg) patterns of
a typical Iberian dataset (including hgs H, T, J, and U). Three new branches
of the mtDNA phylogeny (H1j1, U5b1e, and L2a5) are described for the first
time, but none of these are likely to be related to NS or
Ras/MAPK pathway syndromes when
observed under an evolutionary perspective. Patterns of variation in tRNA
and protein genes, as well as redundant, private and heteroplasmic variants,
in the mtDNA genomes of patients were as expected when compared with the
patterns inferred from a worldwide mtDNA phylogeny based on more than 8700
entire genomes. Moreover, most of the mtDNA variants found in patients had
already been reported in healthy individuals and constitute common
polymorphisms in human population groups. Conclusions/Significance As a whole, the observed mtDNA genome variation in the NS patients was
difficult to reconcile with previous findings that indicated a pathogenic
role of mtDNA variants in NS.

Abstract
Hashimoto encephalopathy is a steroid-responsive encephalopathy associated with elevated blood concentrations of antithyroid antibodies. The patients are usually euthyroid or mildly hypothyroid. The clinical picture is pleomorphic, presenting with variable symptoms ranging from behavioral and cognitive changes, myoclonus, seizures, pyramidal tract dysfunction, involuntary movements, and cerebellar signs to psychosis and coma, with relapsing and progressive course. The diagnosis is often overlooked at presentation but is crucial, given that this is a treatable disease. Described here, with a literature review, is the youngest patient reported to date with Hashimoto encephalopathy.

Abstract
There is evidence that valproic acid causes a reduction of serum biotinidase enzyme activity. We determined the serum concentration of antiepileptic drugs, transaminases, gamma-glutamyl transferase, ammonia, and biotinidase enzyme activity in 57 children treated with valproic acid, in 17 children treated with carbamazepine, and in 75 age- and sex-matched healthy controls. There were no significant differences in the serum biotinidase enzyme activity between the patients treated with valproic acid, the patients treated with carbamazepine, and the control group. Hyperammonemia was detected in 8 patients treated with valproic acid. Hair loss was observed in 3 female patients treated with valproic acid, and the alopecia disappeared with the oral administration of biotin (10 mg/ d) in 3 months. These results suggest that the treatment with valproic acid does not alter the serum biotinidase enzyme activity.

Abstract
We report an infant with complex I deficiency of the mitochondrial respiratory chain whose most conspicuous symptom at presentation was an Ohtahara syndrome. Review of the literature suggest that association of these two conditions is extremely rare. Despite the few cases reported, in our view Ohtahara syndrome should be considered as one of the forms of presentation of mitochondrial dysfunction.

Abstract
AIM The aim of this study was to evaluate the usefulness of cerebral blood flow velocity in the middle cerebral artery measured by transcranial Doppler as criteria to therapeutic action in communicating hydrocephalic children. METHODS In eight non-tumoral communicating hydrocephalic infants, ranging from five to 18 months of age, monitored from 18 to 36 months (mean time of follow-up: 24.25 months), cerebrospinal fluid (CSF) oxypurines (hypoxanthine and xanthine) and uric acid levels were compared by means of the Evans' index, the mean weekly increase in cranial circumference, and the transcranial Doppler measurements. RESULTS Results indicate that clinical (mean weekly increase in head circumference), radiological (Evans' index), biochemical (oxypurines and uric acid in the CSF), and hemodynamic (transcranial Doppler) criteria have the same role in monitoring infantile hydrocephalus. CONCLUSION In conclusion the transcranial Doppler measurement can be done noninvasively and examinations can be repeated when needed, obtaining immediate RESULTS Hence, it is the most adequate monitoring technique in clinical practice.

Abstract
INTRODUCTION AND DEVELOPMENT Paediatric neurology is fully aware of the fact that important advances in genetics are being applied to the clinical and prenatal diagnoses of a wide range of diseases. The discovery of new genes related to a growing number of pathologies with neurological implications opens up new diagnostic approaches and provides information that is very useful in the process of detecting carriers and identifying pre-symptomatic individuals. More selective genetic techniques with higher resolutions are increasingly more commonly available in genetic laboratories, as is the possibility of sequencing and searching for specific mutations in certain genes; for some processes their application to clinical practice has made them the initial diagnostic approach. A precise clinical orientation and knowledge of their applications and limitations is essential, and requires an increasingly close relationship between clinicians and geneticists in order to design a tailored diagnostic protocol that offers a rational balance between technical availability, cost, time and relevance of the findings. CONCLUSIONS We discuss some of the current aspects and considerations about advances in specific neuropaediatric pathologies, within the group of neuromuscular disorders, mental retardation, autism spectrum disorders and epilepsy.

Abstract
The concentration levels of serum free thyroxine, serum free triiodothyronine, and thyroid-stimulating hormone were measured in 20 children receiving carbamazepine, 32 children receiving valproic acid, and 5 children receiving phenobarbital at the following times: (1) during chronic treatment, and (2) 3 months after the end of treatment with antiepileptic drugs. Patients during chronic treatment revealed significant changes in serum thyroid hormones, especially the children treated with carbamazepine and valproic acid. A number of children receiving long-term therapy with the two last antiepileptic drugs had varying grades of subclinical hypothyroidism. Three months after the end of treatment, a complete return to normal of all parameters was observed. These data demonstrate that the changes induced by these drugs are transient and reversible.
