Variants in the degron of AFF3 are associated with intellectual disability, mesomelic dysplasia, horseshoe kidney, and epileptic encephalopathy.

Am J Hum Genet 2021 May;108(5):857-873

GeneDx, Gaithersburg, MD 20877, USA.

The ALF transcription factor paralogs, AFF1, AFF2, AFF3, and AFF4, are components of the transcriptional super elongation complex that regulates expression of genes involved in neurogenesis and development. We describe an autosomal dominant disorder associated with de novo missense variants in the degron of AFF3, a nine amino acid sequence important for its binding to ubiquitin ligase, or with de novo deletions of this region. The sixteen affected individuals we identified, along with two previously reported individuals, present with a recognizable pattern of anomalies, which we named KINSSHIP syndrome (KI for horseshoe kidney, NS for Nievergelt/Savarirayan type of mesomelic dysplasia, S for seizures, H for hypertrichosis, I for intellectual disability, and P for pulmonary involvement), partially overlapping the AFF4-associated CHOPS syndrome.

Clin Exp Metastasis 2021 May 7. Epub 2021 May 7.

Moffitt Cancer Center, Department of Pathology, 12902 Magnolia Drive, Tampa, FL, 33612, USA.

The clinical importance of metastatic spread of cancer has been recognized for centuries, and melanoma has loomed large in historical descriptions of metastases, as well as the numerous mechanistic theories espoused. The "fatal black tumor" described by Hippocrates in 5000 BC that was later termed "melanose" by Rene Laennec in 1804 was recognized to have the propensity to metastasize by William Norris in 1820. And while the prognosis of melanoma was uniformly acknowledged to be dire, Samuel Cooper described surgical removal as having the potential to improve prognosis. Read More

Crossing the boundaries: IL-23 and its role in linking inflammation of the skin, gut and joints.

Rheumatology (Oxford) 2021 May 7. Epub 2021 May 7.

Department of Internal Medicine and Pediatrics, UZ Ghent, Ghent University, Ghent, Belgium.

Several lines of evidence point towards the central role of interleukin 23 (IL-23) as a crucial inflammatory mediator in the pathogenesis of spondyloarthritis-a group of inflammatory arthritic diseases whose symptoms span the skin, gastrointestinal tract and joints. While therapeutic blockade of IL-23 proved successful in the treatment of inflammatory bowel disease, psoriatic skin disease and peripheral spondyloarthritis it failed in patients suffering from spondyloarthritis with predominantly axial involvement. Here we review state-of-the-art discoveries on IL-23 signalling pathways across target tissues involved in spondyloarthritis. Read More
