Abstract
Mitral arcade is a rare entity that is mostly reported in pediatric patients. We present the first 2 adult cases of mitral arcade in combination with tricuspid dysplasia, left ventricular noncompaction, and short-chain acyl-CoA deficiency in 2 brothers. We examined clinical and echocardiographic data on 2 brothers with a combination of short-chain acyl-CoA deficiency, mitral arcade, tricuspid dysplasia, and left ventricular noncompaction (LVNC), highlighting their clinical course and outcomes. Two-dimensional and 3-dimensional transthoracic echocardiography revealed direct attachment of the papillary muscles to the mitral leaflets, namely mitral arcade, as well as mild mitral regurgitation along with LVNC and tricuspid dysplasia. Over the past 7 years, both brothers have remained asymptomatic with excellent exercise capacity (13 and 10 metabolic equivalents (METS), respectively). Mitral and tricuspid regurgitation remain mild with unchanged left ventricular function (ejection fraction: 65% and 59%). In conclusion, we highlight 2 cases with a constellation of pathology including short-chain acyl-CoA deficiency, mitral arcade, tricuspid dysplasia, and LVNC, which has never been described before.

Abstract
Clustered regularly interspaced short palindromic repeats (CRISPR) technology has greatly accelerated the field of strain engineering. However, insufficient efforts have been made toward developing robust multiplexing tools in Saccharomyces cerevisiae. Here, we exploit the RNA processing capacity of the bacterial endoribonuclease Csy4 from Pseudomonas aeruginosa, to generate multiple gRNAs from a single transcript for genome editing and gene interference applications in S. cerevisiae. In regards to genome editing, we performed a quadruple deletion of FAA1, FAA4, POX1 and TES1 reaching 96% efficiency out of 24 colonies tested. Then, we used this system to efficiently transcriptionally regulate the three genes, OLE1, HMG1 and ACS1. Thus, we demonstrate that multiplexed genome editing and gene regulation can be performed in a fast and effective manner using Csy4.

Abstract
Succinyl-CoA:3-oxoacid CoA transferase (SCOT, gene symbol OXCT1) deficiency is an autosomal recessive disorder in ketone body utilization that results in severe recurrent ketoacidotic episodes in infancy, including neonatal periods. More than 30 patients with this disorder have been reported and to our knowledge, their heterozygous parents and siblings have had no apparent ketoacidotic episodes. Over 5 years (2008-2012), we investigated several patients that presented with severe ketoacidosis and identified a heterozygous OXCT1 mutation in four of these cases (Case1 p.R281C, Case2 p.T435N, Case3 p.W213*, Case4 c.493delG). To confirm their heterozygous state, we performed a multiplex ligation-dependent probe amplification analysis on the OXCT1 gene which excluded the presence of large deletions or insertions in another allele. A sequencing analysis of subcloned full-length SCOT cDNA showed that wild-type cDNA clones were present at reasonable rates to mutant cDNA clones. Over the following 2 years (2013-2014), we analyzed OXCT1 mutations in six more patients presenting with severe ketoacidosis (blood pH ≦7.25 and total ketone body ≧10 mmol/L) with non-specific urinary organic acid profiles. Of these, a heterozygous OXCT1 mutation was found in two cases (Case5 p.G391D, Case6 p.R281C). Moreover, transient expression analysis revealed R281C and T435N mutants to be temperature-sensitive. This characteristic may be important because most patients developed ketoacidosis during infections. Our data indicate that heterozygous carriers of OXCT1 mutations can develop severe ketoacidotic episodes in conjunction with ketogenic stresses.

Abstract
Mitochondrial 3-hydroxy-3-methylglutaryl CoA synthase (HMCS2) deficiency results in episodes of hypoglycemia and increases in fatty acid metabolites. Metabolite abnormalities described to date in HMCS2 deficiency are nonspecific and overlap with other inborn errors of metabolism, making the biochemical diagnosis of HMCS2 deficiency difficult. Urinary organic acid profiles from periods of metabolic decompensation were studied in detail in HMCS2-deficient patients from four families. An additional six unrelated patients were identified from clinical presentation and/or qualitative identification of abnormal organic acids. The diagnosis was confirmed by sequencing and deletion/duplication analysis of the HMGCS2 gene. Seven related novel organic acids were identified in urine profiles. Five of them (3,5-dihydroxyhexanoic 1,5 lactone; trans-5-hydroxyhex-2-enoate; 4-hydroxy-6-methyl-2-pyrone; 5-hydroxy-3-ketohexanoate; 3,5-dihydroxyhexanoate) were identified by comparison with synthesized or commercial authentic compounds. We provisionally identified trans-3-hydroxyhex-4-enoate and 3-hydroxy-5-ketohexanoate by their mass spectral characteristics. These metabolites were found in samples taken during periods of decompensation and normalized when patients recovered. When cutoffs of adipic >200 and 4-hydroxy-6-methyl-2-pyrone >20 μmol/mmol creatinine were applied, all eight samples taken from five HMCS2-deficient patients during episodes of decompensation were flagged with a positive predictive value of 80% (95% confidence interval 35-100%). Some ketotic patients had increased 4-hydroxy-6-methyl-2-pyrone. Molecular studies identified a total of 12 novel mutations, including a large deletion of HMGCS2 exon 1 in two families, highlighting the need to perform quantitative gene analyses. There are now 26 known HMGCS2 mutations, which are reviewed in the text. 4-Hydroxy-6-methyl-2-pyrone and related metabolites are markers for HMCS2 deficiency. Detection of these metabolites will streamline the biochemical diagnosis of this disorder.

Abstract
The erythromycin precursor polyketide 6-deoxyerythronolide B (6-dEB) is produced from one propionyl-CoA starter unit and six (2S)-methylmalonyl-CoA extender units. In vitro studies have previously demonstrated that the loading module of 6-deoxyerythronolide B synthase (DEBS) exhibits relaxed substrate specificity and is able to accept butyryl-CoA, leading to the production of polyketides with butyrate starter units. We have shown that we can produce butyryl-CoA at levels of up to 50% of the total CoA pool in Escherichia coli cells that overexpress the acetoacetyl-CoA:acetyl-CoA transferase, AtoAD (EC 2.8.3.8), in media supplemented with butyrate. The DEBS polyketide synthase (PKS) used butyryl-CoA and methylmalonyl-CoA supplied in vivo by the AtoAD and methylmalonyl-CoA mutase pathways, respectively, to produce 15-methyl-6-dEB. Priming DEBS with endogenous butyryl-CoA affords an alternative and more direct route to 15-Me-6-dEB than that provided by the chemobiosynthesis method [Jacobsen, J. R., et al. (1997) Science 277, 367-369], which relies on priming a mutant DEBS with an exogenously fed diketide thioester. The approach described here demonstrates the utility of metabolic engineering in E. coli to introduce precursor pathways for the production of novel polyketides.

Abstract
Glutaryl-CoA dehydrogenase deficiency is an inherited neurometabolic disease complicated by precipitation of acute encephalopathic crises during a vulnerable period of brain development. These crises result in bilateral striatal damage and subsequently a dystonic dyskinetic movement disorder. In previous in vitro studies neuronal damage in this disease has been linked to an excitotoxic mechanism mediated in particular by one of the accumulating metabolites, 3-hydroxyglutaric acid. However, nothing is known about the in vivo effects of this organic acid. In the present study, we used a stereotaxic intrastriatal injection technique to investigate the behavioral and neurotoxic effects of 3-hydroxyglutaric acid exposure in rats. Here, we report that 3-hydroxyglutaric acid induced an increase in convulsion frequency and duration as determined by open field measurement. Nissl-stained coronal sections from treated rats revealed a pale lesion in the striatum following 3-hydroxyglutaric acid exposure. N-methyl-D-aspartate (NMDA) receptor blockade by MK-801 and stimulation of GABA(A) receptors by muscimol prevented the induction of convulsions and striatal damage by 3-hydroxyglutaric acid, whereas blockade of non-NMDA receptors by 6,7-dinitroquinoxaline-2,3-dione (DNQX) was not protective. We conclude that 3-hydroxyglutaric acid induces convulsions and striatal damage via initiation of an imbalance in the excitatory glutamatergic and the inhibitory GABAergic neurotransmission, resulting in an enhanced excitatory input in striatal neurons. These results support the hypothesis of NMDA receptor-mediated excitotoxic cell damage in glutaryl-CoA dehydrogenase deficiency and represent the basis for the development of new neuroprotective treatment strategies.

Abstract
Inherited defects in the gene encoding the methylmalonyl-CoA mutase (MCM) result in the mut forms of methylmalonic aciduria (MMA). Twelve mutations have been identified associated with the mut(-) phenotype. We report two novel mutations (K621N and D156N) in a compound heterozygote mut(-) patient. These two mutations and three previously published ones (H627N, A191E, Y231N) were mapped onto a three-dimensional homology model of the human MCM constructed from the crystal structure of the Propionibacterium shermanii enzyme.

Abstract
Propionic acidemia is an inborn error of organic acid metabolism caused by deficiency of propionyl-CoA carboxylase (PCC: E. C. 6. 4. 1. 3.). We have detected three types of mutation in the same exon of the coding sequence of beta-subunit of PCC (beta PCC) from two ethnic background (Caucasians and Japanese): an insertion/deletion which replaces 14 nucleotides with 12 unrelated nucleotides results in the elimination of an Msp I site; a 3-bp inframe deletion results in loss of one of two consecutive isoleucine codons immediately preceding the same Msp I site; the C----T transition results a in loss of the same Msp I site. The insertion/deletion and the C----T transition show high allele frequency in Caucasians (0.32) and in Japanese (0.3), respectively. These results reveal the possibility of the independent origin of the mutation in the two ethnic backgrounds and suggest a key role of this exon in the structure and catalytic function of the beta-subunit of PCC.

Abstract
Urinary organic acid profiles in patients with inherited defects of fatty acid metabolism and ketogenesis are described. Medium-chain acyl-CoA dehydrogenase, short-chain acyl-CoA dehydrogenase, multiple acyl-CoA dehydrogenase, and 3-hydroxy-3-methyl-glutaryl-CoA lyase deficiencies can be recognized at the metabolite level. Data on long-chain acyl-CoA dehydrogenase and systemic carnitine deficiencies are scarce. In the latter disorders, dicarboxylic aciduria is rather nonspecific and points to a modest omega-oxidation of long chain fatty acids.

Abstract
We have developed a method for rapid differential diagnosis of isolated or multiple deficiencies of the 3 mitochondrial biotin-dependent carboxylases: propionyl-CoA (PCC), 3-methylcrotonyl-CoA (MCC) and pyruvate carboxylase (PC), and for simultaneous evaluation of biotin-responsiveness using a single blood sample. Lymphocytes were isolated from heparinized blood and preincubated without and with 10(-5) mol/l biotin in medium before determination of PCC, MCC and PC activities. Plasma was used for estimation of biotin concentration and biotinidase activity. A definitive diagnosis could be made in 7 of 9 patients studied up to now: 4 patients suffered from biotin-nonresponsive isolated PCC-deficiency, and 3 patients from biotin-responsive multiple carboxylase deficiency caused by deficient biotinidase activity. In two patients, a carboxylase deficiency was excluded. These results were confirmed in studies using fibroblasts. In addition, a simple method for detection of deficiency in holocarboxylase synthesis is described.

Abstract
Two pregnancies at risk for glutaric acidemia were monitored. In one, in which the fetus was not affected, glutaric acid was not detected in the amniotic fluid at amniocentesis (15 weeks) and the glutaryl-CoA dehydrogenase activity of cultured amniotic cells was normal. In the other, a marked elevation of glutaric acid in the amniotic fluid, together with deficiency of glutaryl-CoA dehydrogenase in amniotic cells, prompted termination of the pregnancy, and studies on the abortus confirmed the diagnosis of glutaric acidemia. Glutaric acidemia, is, thus, another inborn error of metabolism which can be diagnosed in utero.
