A new study pinpointed that children suffering from Williams syndrome, a rare neurodevelopmental disorder caused by a genetic defect, lack racial stereotyping. In other words they are unable to differentiate between racial and ethnic groups. It does not occur to them that a Caucasian, Black African and East Asian belong to different categories of people, although they can distinguish between gender and age normally.
Because Williams syndrome is caused by a deletion of about 26 genes from the long arm of chromosome 7, it is fair to assume that our neurological capacity to distinguish ethnic or racial groups from one another is located on one or several of these deleted genes on chromosome 7.
