Pathogenic variants in the cohesin loader subunit MAU2 lead to a new Cornelia de Lange Syndrome subtype

This study identifies MAU2 variants as a new cause of Cornelia de Lange Syndrome and describes associated molecular and clinical features.

Clinical, in vitro, and in vivo evidence of WAPL as a novel cohesinopathy gene and phenotypic driver of 10q22.3q23.2 genomic disorder

The paper identifies WAPL as a novel cohesinopathy gene and driver of a genomic disorder, showing its role in developmental delay and other anomalies through clinical, in vitro, and in vivo analyses.

Advancing molecular, phenotypic and mechanistic insights of FGF14 pathogenic expansions (SCA27B)

This study identifies the complete sequences of pathogenic and non-pathogenic FGF14 repeat expansions in patients with cerebellar ataxia, revealing a lower pathogenic threshold and providing mechanistic insights into disease causation.

Next-generation phenotyping integrated in a national framework for patients with ultra-rare disorders improves genetic diagnostics and yields new molecular findings

The paper evaluates a structured diagnostic framework for ultra-rare diseases, showing improved genetic diagnoses and novel gene-disease associations using exome sequencing and AI tools.

Systematic analysis and prediction of genes associated with disorders on chromosome X

The paper systematically analyzes chrX genes to predict disease associations, identifying 235 genes likely involved in disorders and reporting damaging variants in CDK16 and TRPC5 in patients with intellectual disability or autism.

MAU2 and NIPBL variants in Cornelia de Lange syndrome reveal MAU2-independent loading of cohesin and uncover a protective mechanism against early truncating mutations in NIPBL

The paper investigates variants in MAU2 and NIPBL in CdLS, showing NIPBL haploinsufficiency as the main cause and revealing a protective mechanism for NIPBL out-of-frame mutations.

Disruption of the topological associated domain at Xp21.2 is related to gonadal dysgenesis: A general mechanism of pathogenesis

The paper shows that structural variations at Xp21.2 disrupt a TAD boundary, leading to gonadal dysgenesis through altered gene regulation.
