Clinical and Neurodevelopmental Characteristics of Paralogous Gain‐of‐Function Variants at GRIA2 p.Gly792 and GRIA3 p.Gly803

open access: yesClinical Genetics, EarlyView.
Key features of paralogous GRIA2 and GRIA3 gain‐of‐function variants. ABSTRACT GRIA‐related disorders arise from disease‐causing variants in GRIA1, GRIA2, GRIA3, or GRIA4 that encode α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazole propionic acid (AMPA)‐type glutamate receptors (AMPARs).

Six New Cases of 22q13.2 Gain Including TFC20: First Report of Triplication and Smallest Duplication Associated With Neurodevelopmental Delays

open access: yesClinical Genetics, EarlyView.
This study reports six new cases of 22q13.2 duplication and triplication, including the TCF20 gene, associated with neurodevelopmental disorders and various morphological and systemic abnormalities. The findings suggest a variable expressivity, but their complete penetrance remains uncertain compared to well‐established loss‐of‐function variants ...

Diagnosis of Angelman Syndrome, With 66 Years of Delay, Using Hypothesis‐Free DNA Methylation Profiling

open access: yesClinical Genetics, EarlyView.
Hypothesis‐free DNA methylation profiling in a 66‐year‐old male with unexplained neurodevelopmental disorder enabled the exclusion of ZNF142‐related disease (left panel) and led to a retrospective diagnosis of Angelman syndrome, highlighting the diagnostic potential of single‐patient epigenetic screening (right panel).

Unraveling the Role of WDR91: Case Report of a Previously Unrecognized Clinical Entity

open access: yesClinical Genetics, EarlyView.
A novel case is herein described to expand the genetic and clinical spectrum of WDR91 and characterize a previously unrecognized autosomal recessive neurodevelopmental disorder. WDR91 deficiency results in neuronal loss, cortical thinning, and impaired brain development.
