BackgroundMicrodeletions of 2q23.1 disrupting MBD5 and loss of function mutations of MBD5 cause MBD5-Associated Neurodevelopmental disorders (MAND). Nearly all reported patients have been isolated cases of de novo origin. MethodsThis study investigates three families with inherited MBD5 mutations from three different Regional Genetics Centres in the UK. ResultsTwo of the parents in the study had MBD5 deletions in a mosaic form. The parent with an MBD5 deletion in an apparently nonmosaic form has a psychiatric disorder in the absence of developmental delay or dysmorphism. ConclusionsInherited forms of MBD5 deletions are rare, but do occur, especially in a mosaic form. The phenotypic spectrum of MAND may be wider than previously thought.
