TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Microdeletions at 17q21.31 have recently been shown to cause a novel syndrome. Here we identify the reciprocal 17q21.31 duplication syndrome in 4 patients.', 'Patients with the 17q21.31 duplication were identified by screening a large cohort of patients (n = 13,070) with mental retardation and congenital malformation by comparative genomic hybridisation microarray. Parental origin was investigated in 3 patients by quantitative polymerase chain reaction and microsatellite genotyping.', 'In three cases it was possible to show that duplication arose de novo. Intellectual skills range from normal to mild mental retardation. Patients are characterised by poor social interaction, with relationship difficulties, reminiscent of autistic spectrum disorders. Other features are rather variable with no striking common phenotypic features. Parental origin was investigated for 3 patients. In all cases duplication was of maternal origin either through interchromosomal (2 cases) or interchromatid (1 case) rearrangement. The 3 mothers are all carriers of the inverted H2 haplotype, emphasising the role of local genomic architecture alteration as a predisposing factor for this duplication.'] Do 17q21.31 microduplication patients are characterised by behavioural problems and poor social interaction?
OUTPUT:

yes
