STUDY OF ABNORMAL PALMER CREASES IN CHILDREN WITH AUTISM SPECTRUM DISORDER: A CASE-CONTROL STUDY IN NORTH INDIA

Abstract

INTRODUCTION: Autism Spectrum Disorder is a neurodevelopmental disorder characterized mainly by deficits in social and communication patterns. Aberrant gene environment interactions during fetal development leads to formation of minor physical anomalies such as abnormal palmar creases commonly seen in autism spectrum disorder. AIM: To compare the prevalence of abnormal palmar creases in children with autism spectrum disorder and typically developing children. METHODOLOGY:It was a case controlled cross sectional study conducted in departments of Psychiatry and Pediatrics of Pt. B.D. Sharma, PGIMS Rohtak. Fifty children of age 4-16 years with diagnosis of autism spectrum disorder (case group) and fifty typically developing children (control group) were recruited. A digital camera of 13 megapixels was used to click photographs of the palms of children. Palmar crease patterns of fifty children with diagnosis of autism spectrum disorder were compared with the control group. RESULTS:The prevalence of abnormal palmar creases in case group was higher (47%) than in control group (14%).The prevalence of Simian crease in case group was double (22%) as compared to one in control group i.e. 11%. The prevalence of Sydney crease in case group was 21%, while in control group it was only 3%. The prevalence of Suwon crease in case group was 4%,while it was not seen in control group. CONCLUSION:Children with abnormal palmar creases help in early screening of neurodevelopmental disorders such as autism spectrum disorder helping in early management of these children leading to better outcomes and alleviation of parental stress and burden
