Neurodevelopmental Impairment As the Main Phenotypic Hallmark Associated with the Translocation t(7;10)(7p22.3;q26.11)

Abstract

Reported here is a novel patient carrying an unbalanced t (10q26.11-q26.3; 7p22.3) and presenting with a severe intellectual disability with autistic features, abnormalities of muscle tone, and a drug-responsive epilepsy. The prominence of neurological and neurodevelopmental abnormalities in the clinical phenotype highlights a possible pathogenic role for different genes in the involved regions. Hypothetical mechanisms may include a possible gene dosage effect for DOCK1 and/or haploinsufficiency of PRKAR1B SUN1, ADAP1, and GPER1.
