NCT01687842

Brief Summary

Monocentric multidisciplinary study (psychologists, endocrinologists, psychiatrists, and molecular biologists) to characterize social cognition in adolescents with Turner syndrome (TS). Inclusion criteria:

  • Turner syndrome with homogeneous 45,X karyotype.
  • Age between 8 and 18 years.
  • Somatic state compatible with the evaluation.
  • Functional language and IQ ≥ 80 for the transfer tests
  • Informed consent signed by the holders of parental authority, the patient and the mother for her own participation (DNA collection).
  • Affiliation to Social Security (beneficiary or assignee). The primary endpoint will be the overall score to the AQ (Autism Quotient) questionnaire and to the SRS (Social Reciprocity Scale), in comparison to the expected scores for the general population. For patients with scores above the threshold for SRS or QA validation of a possible diagnosis of autism spectrum disorders will be performed with commonly used diagnostic tools (ADIR (Lord et al, 1994), ADOS-G (Lord et al, 1999) and diagnostic criteria of DSM IV-TR). Secondary criteria will include the results of standardized tests to assess autistic features (AQ, ADI-R, ADOS, DSM IV-TR criteria), intellectual efficiency (Wechsler scales), psychiatric comorbidities (Kiddie-SADS) and sociocognitive profile (SpeX test, Social cognition, Perception, eXecutive functions). A DNA sample will be collected from the patient and her mother. The observation period is 2 days for the patient and about 1 hour for the mother. The total duration of the study is 3 years.
