In brief: Trisomy-x
According to lyon hypothesis, mammalian species with multiple x chromosomes will have all x's inactivated except one; normally women have xx genotype thus has only one inactivated x ( barr body), men have xy thus has no inactivated x ( no barr body), your cousin most likely has a karyotype of 47, xxx, thus two barr bodies, so called " super woman", most are normal but a few may have problems.
