In a study initiated by Sébastien Jacquemont from the Service of Medical Genetics in collaboration with the group of Evan Eichler, we investigated the CNV burden of autistic patients and close relatives. We could show that females diagnosed with autism have on average more deleterious mutations in genes involved in neuro-developmental disorders than males, hinting that women can cope with a higher mutational burden than men. Moreover most of the deleterious mutations in genes important for brain function are transmitted by the non-affected mothers, showing that they can tolerate more mutations than the fathers. | In a study initiated by Sébastien Jacquemont from the Service of Medical Genetics in collaboration with the group of Evan Eichler, we investigated the CNV burden of autistic patients and close relatives.

It has long been observed that males are more affected by neuro-developmental disorders such as autism than females.

It has long been observed that males are more affected by neuro-developmental disorders such as autism than females. In a study initiated by Sébastien Jacquemont from the Service of Medical Genetics in collaboration with the group of Evan Eichler from the University of Washington, we investigated the CNV burden of autistic patients and close relatives. We could show that females diagnosed with autism have on average more deleterious mutations in genes involved in neuro-developmental disorders than males, hinting that women can cope with a higher mutational men. With the same mutational burden, males tend to be more often diagnosed than females. This is unlikely to be due to social factors only, because most of the deleterious mutations in genes important for brain function are transmitted by the non-affected mothers, showing that they can tolerate more mutations than the non-affected fathers.
