SPANX-B and SPANX-C (Xq27 region) gene dosage analysis in Down’s syndrome subjects with undescended testes
2009
Down’s syndrome (DS) is one of the most common numer- ical chromosomal aberrations, usually caused by trisomy of chromosome 21, and is frequently complicated with congen- ital heart defects, duodenal obs truction and other conditions including undescended testis (UDT) (Fonkalsrud 1970). The incidence of undescended testes in DS was reported to be 6.52% (Chew and Hutson 2004) while the incidence of UDT in the first year is approximately 0.2%–0.8% in the nor- mal population (Benson et al . 1991; Ichiyanagi et al . 1998). Rapley et al . (2000) provided evidence for a testicular germ- cell tumours (TGCT) predisposition locus at Xq27; the au- thors obtained an hlod score of 4.7 from families wit…
Attribution style in adolescents with Down’s sindrome
2005
Educational research places emphasis on the fact that individuals who have experienced repeated failures may develop an attribution profile characterized by a bias towards primarily external causes. The aim of this study is to compare the attribution style of adolescents with Down's syndrome with that of normal children and adolescents matched for mental and chronological age; three groups consisting of 10 participants each were employed, an experimental group and two control groups were employed. The experimental group were Down's syndrome adolescents. Participants in the first control group were matched to the experimental groups for mental age, and those in the second for chronological a…
