THERE IS A GROWING THEORIES THAT MOST CASES OF AUTISM AND ASD DERIVE FROM A COMBINATION OF GENETIC AND ENVIRONMENTAL FACTORS.GENETIC FACTORS MAY SET THE STAGE FOR ASD,YET IN MANY INDIVIDUAL CASES, ENVIROMENTAL FACTORS APPEARS TO BE NECESSARY TRIGGER WHEREBY GENES THEN CAUSE THE DISORDER.MENTAL AND EMOTIONAL DYSFUNCTION WHICH RESULT IN ALTERATION A CHILD'S BRAIN,SCIENTIST HAVE LONG THOUGHT THAT AUTISM IS A GENETIC DISEASE.YET GENE RESEARCH HAS BEEN UNABLE TO IDENTIFY A SPECIFIC CHROMOSOME OR LOCATION ON A GENE THAT IS THE SITE OF A PRIMARY AUTISM DEFECT.THESE CHILDREN RARELY PRESENT FACIAL AND BIDILY DYSMORPHIC FEATURES CHARACTERISTIC OF THE CHILDREN WITH CHROMOSOMAL DEFECTS THAT OCCUR IN VERY EARLY GESTATION SUCH AS DOWN, WILLIAMS,AND FRAGILE X CHILDREN.ALTHOUGH A SPECIFIC UNDERSTANDING OF HOW GENETICS CONTRIBUTES TO AUTISM STILL LACKING,IT IS CLEAR THAT THERE IS LIKELY TO BE A GENETIC '' PREDISPOSITION'' OR VULNERABILITY IN MANY ASD CHILDREN.WE LOVE TO SEE MORE STUDIES ABOUT IMMUNE -RELATED GENES APPEAR IN THE AUTISM LITERATURE,I WILL OFFER MORE INFORMATION IN OUR NEXT INTERNATIONAL AUTISM CONFERENCEIN HONDURAS.
