neurodevelopmental disorder caused by a deletion of around 27 genes in chromosome 7, characterized by a broad forehead, underdeveloped chin, short nose, full cheeks, challenges with visual tasks, increased empathy and decreased aggression
Rett syndrome
genetic brain disorder
Angelman syndrome
genetic condition in humans
DiGeorge syndrome
T cell deficiency disease that is the result of a large deletion of chromosome 22, which includes the DGS gene needed for development of the thymus and related glands with subsequent lack of T-cell production

genetic disease
Sotos syndrome
