title: Twenty-five additional cases of trisomy 9 mosaic: Birth information, medical conditions, and developmental status.
abstract: Limited literature exists on children and adults diagnosed with the mosaic form of trisomy 9. Data from the Tracking Rare Incidence Syndromes (TRIS) project has provided physical characteristics and medical conditions for 14 individuals. This article provides TRIS Survey results of 25 additional cases at two data points (birth and survey completion) as well as developmental status. Results confirmed a number of phenotypic features and medical conditions. In addition, a number of cardiac anomalies were reported along with feeding and respiratory difficulties in the immediate postnatal period. In addition, developmental status data indicated a range in functioning level up to skills in the 36 and 48-month range. Strengths were also noted across the sample in language and communication, fine motor and social-emotional development. Implications for professionals caring for children with this genetic condition are offered.
