Menke-Hennekam Syndrome: A Literature Review and a New Case Report.

Children (Basel) 2022 May 22;9(5). Epub 2022 May 22.

Department of Pediatrics, Carol Davila University of Medicine and Pharmacy, "Grigore Alexandrescu" Emergency Hospital for Children, 011743 Bucharest, Romania.

The CREB-binding protein ( and genes are two commonly expressed genes whose products possess acetyltransferase activity for histones and various other proteins. Mutations that affect these two genes are known to cause Rubinstein-Taybi syndrome (RTS); however, with the application of whole exome sequencing (WES) there were reports of variants that affect specific regions of exon 30 or 31 of these two genes but without the specific phenotype of RTS.

The natural history of adults with Rubinstein-Taybi syndrome: a families-reported experience.

Eur J Hum Genet 2022 Apr 6. Epub 2022 Apr 6.

Department of Paediatrics, Amsterdam UMC-Location AMC, Amsterdam, The Netherlands.

The existing knowledge about morbidity in adults with Rubinstein-Taybi syndrome (RTS) is limited and detailed data on their natural history and response to management are needed for optimal care in later life. We formed an international, multidisciplinary working group that developed an accessible questionnaire including key issues about adults with RTS and disseminated this to all known RTS support groups via social media.

Institute for Genetic and Biomedical Research (IRGB), National Research Council (CNR), 56124 Pisa, Italy.

Cornelia de Lange syndrome (CdLS) is a rare multiorgan developmental disorder caused by pathogenic variants in cohesin genes. It is a genetically and clinically heterogeneous dominant (both autosomal and X-linked) rare disease. Increasing experimental evidence indicates that CdLS is caused by a combination of factors, such as gene expression dysregulation, accumulation of cellular damage and cellular aging, which collectively contribute to the CdLS phenotype.

Leveraging the Mendelian disorders of the epigenetic machinery to systematically map functional epigenetic variation.

Elife 2021 08 31;10. Epub 2021 Aug 31.

Department of Genetic Medicine, Johns Hopkins University School of Medicine, Baltimore, United States.

Although each Mendelian Disorder of the Epigenetic Machinery (MDEM) has a different causative gene, there are shared disease manifestations. We hypothesize that this phenotypic convergence is a consequence of shared epigenetic alterations. To identify such shared alterations, we interrogate chromatin (ATAC-seq) and expression (RNA-seq) states in B cells from three MDEM mouse models (Kabuki [KS] type 1 and 2 and Rubinstein-Taybi type 1 [RT1] syndromes).
