Abstract
Chromosome analysis of a moderately mentally retarded female revealed a 47,XX,+G? karyotype. Giemsa-trypsin banding showed the extra chromosome to be a deleted chromosome 15 (47,XX,+15q-). This case points out the importance of cytogenetic studies in moderately retarded individuals without significant physical anomalies.
摘要
对一名中度智力发育迟缓女性进行的染色体分析显示其核型为47,XX,+G?。吉姆萨-胰蛋白酶显带显示额外的染色体是一条缺失的15号染色体(47,XX,+15q-)。该病例指出了细胞遗传学研究在无明显身体异常的中度智力发育迟缓个体中的重要性。
