High levels of/luctuating asym1netry in an organism suggest a low capacity to hii/fer the environmental stressor inte1ferring with the genetically determined
"progra1n of development". The pres en ce qf ohstetric complications and jluctuating asymmet1y was assessed in a group qf 20 autistic patients and 20 non-autistic, non-psychotic patíents studied wítb ttest. Fluctuating asymmetry was measured for two independent, continous, ermatoglyphic traíts (a-b ridge count and atd angle) using tbe absolute va!ues qf right minus lejt dif./erences. These results suggest that autístic patients have a more frequent histo1y ql obstetric complications and that they could present a greater vulnerahility to environmental stressors, expressed as a greater degree q/jluctuating asymmetry.
