Inborn errors of metabolism (IEM) have a characteristic clinical presentation overlapping with infection and intoxication. Diagnostic modalities for IEM vary from biochemical to molecular methods including next-generation sequencing. Therapeutic options including substrate restriction, enzyme replacement, chaperone administration, and organ transplant are promising for management of patients with IEM. Prenatal diagnosis and newborn screening help to reduce the societal burden as well as the morbidity due to IEM. IEM occur in India, and the need of the time is to have large diagnostic and screening programs to dilute the gene pool.

Background: Aromatic L-amino acid decarboxylase (AADC) deficiency is a rare life-threatening inborn error of neurotransmitter biosynthesis. It is characterized by deficient biosynthesis of neurotransmitters dopamine and serotonin, leading to catecholamines deficiency and sympathetic deprivation, while the parasympathetic system remains functional. Since 2012, gene therapy has led to clinical improvements in symptoms and motor function with a severe phenotype.

Background: Ataxia telangiectasia mutated (ATM) kinase plays a critical role in DNA double-strand break (DSB) repair. Ataxia telangiectasia (A-T) patients exhibit abnormalities in immunoglobulin isotype expression and class switch recombination (CSR). This study investigates the role of residual ATM kinase expression and activity in the severity of A-T disease.

Hereditary tyrosinemia type 1 (HT-1) is an inborn error of metabolism caused by a defect in tyrosine (tyr) degradation. This defect results in the accumulation of succinylacetone (SA), causing liver failure with a high risk of hepatocarcinoma and kidney injury, leading in turn to Fanconi syndrome with urine loss of phosphate and secondary hypophosphatemic rickets (HR). HT-1 diagnosis is usually made in infants with acute or chronic liver failure or by neonatal screening programs.

Background: AADCd is a rare neurometabolic disorder presenting in infancy. Children with AADCd have motor dysfunction and development delays that result in the need for lifelong care; quality of life is greatly impacted. Current characterizations of health-related quality of life and associated health state utilities (HSUs) may be underestimated in AADCd.

We present the case of a toddler displaying neuroregression post-acute gastroenteritis, initially suggesting neurodegenerative disorders. Further investigations showed atypical results-neuroimaging was inconsistent with suspected disorders, while fundus evaluation, evoked potentials and nerve conduction velocity were normal. Specialised tests using gas chromatography mass spectrometry and tandem mass spectrometry identified methylmalonic acidaemia (MMA), implicating abnormal neurometabolism.
