The Mediator multiprotein complex functions as a regulator of RNA polymerase II-catalyzed gene transcription. In this study, exome sequencing detected biallelic putative disease-causing variants in MED27, encoding subunit 27, 16 patients from 11 families with novel neurodevelopmental syndrome. Patient phenotypes are highly homogeneous, including global developmental delay, intellectual disability, axial hypotonia distal spasticity, dystonic movements, and cerebellar hypoplasia. Seizures...

Abstract MED27 is a subunit of the Mediator multiprotein complex, which involved in transcriptional regulation. Biallelic variants have recently been suggested to be responsible for an autosomal recessive neurodevelopmental disorder with spasticity, cataracts and cerebellar hypoplasia. We further delineate clinical phenotype MED27-related disease by characterizing radiological features 57 affected individuals from 30 unrelated families biallelic variants. Using exome sequencing extensive...

Gangliosidoses are a group of rare lysosomal storage diseases (LySD) involving the accumulation lipids in multiple organ systems, including central and peripheral nervous systems. These disorders inherited an autosomal recessive pattern broadly grouped into 2 types. GM1 gangliosidoses (GM1) due to deficiency enzyme β-galactosidase, GM2 (Tay-Sachs, AB variant, Sandhoff disease) β-hexosaminidase. GM1, first described biochemically by Dr. John S. O'Brien 1960s, is estimated occur 1...

PurposeWe sought to delineate the genotypic and phenotypic spectrum of female male individuals with X-linked, MSL3-related disorder (Basilicata–Akhtar syndrome).MethodsTwenty-five (15 males, 10 females) causative variants in MSL3 were ascertained through exome or genome sequencing at ten different centers.ResultsWe identified multiple variant types (ten nonsense, six frameshift, four splice site, three missense, one in-frame-deletion, multi-exon deletion), most proven be de novo, clustering...

Pediatric cerebral aneurysms are rare, and pediatric anterior choroidal artery very rarely reported. A 14-month-old male with no personal or family history of connective tissue disorders Moyamoya disease presented a right temporal intracerebral hemorrhage intraventricular extension. CTA was negative for vascular pathology, but digital subtraction angiography revealed an aneurysm that successfully coiled. This case underscores the importance performing in children presenting concerning...
