Previous research has tended to include small samples and diverse measures, which limits the generalisability of findings.

It was hypothesised that each syndrome group would evidence a degree of specificity in autistic characteristics. To test this hypothesis, a classification algorithm via support vector machine (SVM) learning was applied to scores from over 1500 individuals diagnosed with one of the thirteen genetic syndromes and autistic individuals who did not have a known genetic syndrome (ASD; <jats:italic>n<\/jats:italic>\u2009=\u2009254).

Syndrome groups such as Angelman, fragile X, Prader\u2013Willi, Rubinstein\u2013Taybi and Cornelia de Lange showed greater phenotypic specificity than groups such as Cri du Chat, Lowe, Smith\u2013Magenis, tuberous sclerosis complex, Sotos and Phelan-McDermid.
