Biomarker for diagnosing autism spectrum disorder

Abstract

The application is about a method for diagnosing autism spectrum disorder (ASD) in a human subject, comprising providing a device comprising a reagent for determining the concentration of arginine vasopressin (AVP) in a biological sample from the subject; and measuring the concentration of AVP in the sample using the device. Disclosed is also a method for diagnosing ASD, comprising providing a first device comprising a reagent for determining a concentration of AVP and a second device comprising a reagent for determining a concentration of one or more analytes selected from arginine vasopressin receptor 1a and oxytocin receptor, to determine the concentrations of AVP and of the one or more analytes. Disclosed is also a method of predicting severity of ASD in a male human subject, comprising providing a device for determining the concentration of AVP in cerebrospinal fluid, said device comprising a reagent for determining presence or absence of AVP; and measuring the concentration of AVP in a biological sample from the subject using the device. Disclosed is also a method of predicting likelihood of an ASD in a human subject, comprising providing a device for determining the concentration of AVP in cerebrospinal fluid, said device comprising a reagent for determining presence or absence of AVP; and measuring the concentration of AVP in cerebrospinal fluid using the device.
