17q23.2q23.3 de Novo Duplication
Chromosomal rearrangements involving 17q23 have been described rarely. Deletions at 17q23.1q23.2 have been reported in individuals with developmental delay and growth retardation, whereas duplications at 17q23.1q23.2 appear to segregate with clubfoot. We report a 7.5-year-old boy with speech and…

AMPA-Receptor Specific Biogenesis Complexes Control Synaptic Transmission and Intellectual Ability
AMPA-type glutamate receptors (AMPARs), key elements in excitatory neurotransmission in the brain, are macromolecular complexes whose properties and cellular functions are determined by the co-assembled constituents of their proteome. Here we identify AMPAR complexes that transiently form in the…

Homozygous Deletion of Exons 2 and 3 of NPC2 Associated with Niemann–Pick Disease Type C
Niemann–Pick disease type C (MIM 607625; NP-C) is an autosomal recessive, lysosomal storage disorder caused by impaired cholesterol and glycolipid trafficking due to pathogenic variations in either NPC1 (accounting for more than 95% of cases) or NPC2 [Park et al., 2003]. Here we report the first…

Molecular, Biochemical, and Structural Analysis of a Novel Mutation in Patients with Methylmalonyl-CoA Mutase Deficiency
Methylmalonic aciduria (MMA) is an inborn error of metabolism resulting from genetic defects in methylmalonyl-CoA mutase (MCM). We found one homozygous nucleotide change in intron 12 of the MUT gene (c.2125-3 C > G).

Unraveling Cellular Phenotypes of Novel TorsinA/TOR1A Mutations
Here, we report two new, putative TOR1A mutations (p.A14_P15del and p.E121K) that we examined functionally in comparison with wildtype (WT) protein and two known mutations (E and p.R288Q).

Diagnostic Difficulties in Krabbe Disease: A Report of Two Cases and Review of Literature
Globoid cell leukodystrophy (GLD, also known as Krabbe disease), whose pathophysiology is still not completely elucidated, is an inherited, metabolic, and neurodegenerative disease, caused by the deficiency of β-galactocerebrosidase (GALC) or in very rare cases by lack of active saposin A. We…
