KBG syndrome is a rare genetic disorder, due to a mutation of ANKRD11, characterized by specific craniofacial dysmorphism, short stature and macrodontia of upper central incisors, intellectual disability and skeletal anomalies. We report a de novo mutation of ANKRD11 gene in a 7-years old girl, affected by KBG syndrome with bilateral conductive hearing loss. The aim of this article was to review the audiological findings of this syndrome.

Rationale: KBG syndrome is a rare, autosomal dominant neurodevelopmental disorder characterized by developmental delay, macrodontia, distinctive facial features, and a range of systemic manifestations.
Patient Concerns: We report a pediatric patient with a history of global developmental delay, autism spectrum disorder, sensorineural hearing loss, and spastic diplegia who developed episodic, unilateral dystonic spells beginning at age 7, leading to impaired mobility.
Diagnoses: Initial genetic testing revealed a maternally inherited 3p26 duplication, which did not fully account for the patient's clinical presentation.

This study was aimed at assessing the diagnostic utility of whole genome sequence analysis in a well-characterised research cohort of individuals referred with a clinical suspicion of Cornelia de Lange syndrome (CdLS) in whom prior genetic testing had not identified a causative variant. Short-read whole genome sequencing was performed on 195 individuals from 105 families, 108 of whom were affected. 100/108 of the affected individuals had prior relevant genetic testing, with no pathogenic variant being identified.

The number of people with HIV (PWH) in Africa is rising due to population growth and antiretroviral therapy (ART) availability, with diffuse large B-cell lymphoma (DLBCL) a major cause of mortality. HIV and ART alter DLBCL tumor biology, but few studies of DLBCL include PWH or African patients, limiting translation of emerging treatment strategies. Here, we performed whole exome sequencing of 48 tumors (40 HIV-positive [HIV+]) with paired germline of DLBCL patients from Malawi and South Africa.

The KBG syndrome (KBGS) affects several systems caused by the mutation of the gene. The main manifestations of KGBS included hearing loss, feeding difficulties, craniofacial abnormalities, tooth deformity, and developmental delay (delayed overall development, convulsions, and intellectual abnormalities). Only 10%-26% of patients with KBG syndrome have congenital heart disease, including atrial and ventricular septal defects.

ANKRD11 haploinsufficiency is implicated in KBG syndrome, characterized by intellectual disability, autism spectrum disorders, and skeletal abnormalities. While mutations are linked to a distinct clinical disorder, they also appear in KBG-like cases, suggesting shared molecular pathways. Here, we show that ANKRD11-deficient neural cells exhibit reduced ribosomal RNA (rRNA) and translation.
