Angelman syndrome and isovaleric acidemia: What is the link?
We report a toddler affected with Angelman syndrome and isovaleric acidemia (IVA). Such association was due to paternal uniparental isodisomy (UPD) of chromosome 15 in which the proband inherited two paternal copies of an IVA gene point mutation. As both

Heterozygous Variants in LRP1 Cause a Neurodevelopmental Disorder With Congenital Heart Defects
ABSTRACT LRP1 encodes the low‐density lipoprotein (LDL) receptor‐related protein 1 (LRP1), a transmembrane protein involved in endocytosis and activation of multiple signaling pathways. LRP1 variants have been implicated in the pathogenesis of congenital heart defects (CHD), Alzheimer's disease, and neurodevelopmental disorders (NDD).

Dissociation of AGAT, GAMT and SLC6A8 in CNS: Relevance to creatine deficiency syndromes
AGAT and GAMT, the two enzymes of the creatine synthesis pathway, are well expressed within CNS, suggesting autonomous brain creatine synthesis. This contradicts SLC6A8 deficiency, which causes creatine deficiency despite CNS expression of AGAT and GAMT.

ABSTRACT Autoinflammatory disorders (AIDs) are a clinically heterogeneous group of inborn errors of immunity primarily caused by dysregulation in the innate immune system. Clinical diagnosis is often challenging due to clinical heterogeneity and the overlapping phenotypes with other inborn errors of immunity and monogenic conditions that mimic AIDs ...

Mucopolysaccharidosis IVA (MPS IVA) is a lysosomal storage disease caused by mutations in the gene encoding for the hydrolase N-acetylgalactose-6-sulfate sulfatase (GALNS). GALNS deficiency leads to a progressive buildup of partially degraded chondroitin-

ABSTRACT Mucopolysaccharidoses (MPS) are lysosomal storage disorders characterized by the accumulation of glycosaminoglycans (GAGs), which can lead to cytoplasmic alterations in leukocytes. The objective of this study was to characterize leukocyte inclusions in patients with different types of MPS and assess their diagnostic relevance.

Treatment of inborn errors of metabolism [PDF]
Inborn errors of metabolism (IEM), though individually rare are collectively common. Average incidence of 50+ common IEMs is considered to be approx 1 in 1,000 live births. With annual birth rate of approximately 25 million babies in India, we can expect at least 25,000 babies being born with IEM in India and hence it is a significant burden to the ...
