Unexpected elevation in valproic acid concentration and agranulocytosis in a patient with short-chain acyl-CoA dehydrogenase deficiency

Early detection of disabling diseases, prior to clinical manifestations, is the primary goal of newborn screening (NS). Indeed, the required number of core and secondary conditions selected for screening panels is increasing in many countries. Furthermore, newborn screening can lead to diagnosis of maternal diseases such as vitamin B12 deficiency or 3-MethylcrotonylCoA-carboxylase deficiency (3MCC). NS became mandatory in Sicily in December 2017. Here we report NS data collected between December 2017 and April 2020. Our results show that tandem mass spectrometry is a powerful tool for discovery of underestimated disease in newborns and their family members. Our panel included short chain acyl-CoA dehydrogenase deficiency (SCADD). Here, we report that results of our investigation led to reassessment of SCADD prevalence in our population. The infant and adult patients diagnosed in our study had previously not shown overt symptoms.

AbstractShort-chain acyl-CoA dehydrogenase deficiency (SCADD) is a mitochondrial fatty acid metabolism disorder, which results in the accumulation of butyrylcarnitine and ethylmalonic acid in blood and urine. Evidence of genotype/phenotype correlation and neuroimaging characteristics is limited compared with other inborn errors of metabolism. We report a male patient with SCADD who initially presented with seizures, metabolic acidosis, microcephaly, and developmental delay with gradual amelioration of most symptoms. MRI/MRS revealed extended multifocal leukoencephalopathy, disturbed myelination, and abnormal brain energy metabolism with low choline/creatine ratio, which indicate the need for MRI/MRS follow-up even for asymptomatic patients with SCADD.
