Objective: This study was undertaken to characterize the clinical and genetic features of patients with 22q11.2 deletion syndrome (22q11.2DS) and generalized epilepsy compared with 22q11.

Purpose: is one of the most frequently mutated genes in intellectual disability cohorts. Thus, far few adult-aged patients with -related disorder have been described, which limits our understanding of the disease's natural history and our ability to counsel patients and their families.

Methods: Data on patients aged 18+ years with -related disorder were collected through an online questionnaire completed by clinicians and parents.

Neurodevelopmental disorder with or without autism or seizures (NEDAUS) is a neurodevelopmental disorder characterized by global developmental delay, speech delay, seizures, autistic features, and/or behavior abnormalities. It is caused by CUL3 (Cullin-3 ubiquitin ligase) haploinsufficiency. We collected clinical and molecular data from 26 individuals carrying pathogenic variants and variants of uncertain significance (VUS) in the CUL3 gene, including 20 previously unreported cases.

Article Synopsis
  • - Microtubule affinity-regulating kinase 2 (MARK2) is crucial for neurons to develop properly, and variants in MARK2 have been linked to autism spectrum disorder (ASD) and other neurodevelopmental issues, with most being loss-of-function mutations.
  • - A study analyzed 31 individuals with MARK2 variants showing ASD along with unique facial features, finding that the loss of MARK2 disrupts early neuron development and leads to abnormal growth patterns in neural cells.
  • - Research using iPSC models and MARK2-deficient mice highlighted the link between MARK2 loss and issues in neuronal function, connecting it to the reduction of the WNT/β-catenin signaling pathway, while suggesting lithium as a potential treatment

Biallelic variants in the ERLIN1 gene were recently reported as the cause of two motor neuron degeneration diseases, SPG62 and a recessive form of amyotrophic lateral sclerosis. However, only 12 individuals from five pedigrees have been identified so far. Thus, the description of the disease remains limited.
