Quality of life in Turner syndrome is related to chromosomal constitution: implications for genetic counselling and management.

Issues of self-appraisal, friendships and academic attainments are uniquely salient for all adolescents. For girls with Turner syndrome, social problems and learning difficulties often become more serious at this time, yet may be unacknowledged by those responsible for paediatric care because their focus is on growth and sexual maturation. Data on the social and educational adjustment of 110 45,X (monosomic) females aged between 6 and 25 years is presented. Detailed information on the patients' precise karyotype was used to demonstrate systematic differences in adjustment between those whose single X chromosome was maternally derived and those in whom it was paternal. Implications for educational support and parental guidance are discussed.
