ASSOCIATION OF OXYTOCIN RECEPTOR (OXTR) GENE POLYMORPHISMS WITH
AUTISM SPECTRUM DISORDER (ASD): A CASE-CONTROL STUDYWITH CLINICAL

A
utism spectrum disorder (ASD) is a group of sex biased neurodevelopmental disorders characterized by
core deficits in social behavior, communication and behavioral flexibility. Several lines of evidence in-
dicate that oxytocin signaling through its receptor (OXTR), is essential in a wide range of social behaviors.
Variable clinical profile of ASD with unique presentation of symptoms was found in our study. 92.23% of the
ASD patients (n=103), than the control groups (n=30) were found to have significant (p<0.0001) social inter-
action difficulties. Along with that common developmental concerns significantly associated with language
impairments (p<0.001), behavioral abnormalities like hypo or hyperactivity (p<0.003), repetitive behavior, re-
sistance to change (p<0.001), self-hurting activities (p<0.0001). Co-morbidities as depression (p<0.01), dyslexia
(p<0.0001), intellectual disability (p<0.001), sleep disturbance (p<0.001) are found to be significantly associ-
ated with ASD, which is co-related with anxiety and behavioral problems. Early recognition of symptoms and
the risk factors would help in appropriate therapeutic intervention resulting in favorable outcome. In attempts
to determine whether genetic variations in the oxytocin signaling system contribute to ASD susceptibility, we
have investigated the role of OXTR variants in ASD development in our Bengali of Bangladesh (BEB) population
of Chittagong region by analyzing four OXTR variants (rs53576, rs2254298, rs2228485, rs237911) through PCR-
RFLP method based on case-control study (37 cases, 15 controls). A significant (p<0.05) frequency for OXTR
rs53576 AA risk allele was found to be associated with ASD compare to controls which is consistent with the
previous study in Chinese but Caucasian and Japanese population. No significant association has been found
for OXTR variants (rs2254298, rs2228485, rs237911) in this study. These findings suggested to further investi-
gate in a larger sample size on OXTR rs53576 polymorphism towards ASD in overall BEB population as well as
ethnic group to open new avenue for clinical marker development for ASD diagnosis and treatment.
