We report 23 cases of small supernumerary chromosome examined at the Medical Genetics Center of Marseille. Genetic counselling is depending on the origin of the additional chromosomal material. Among the different cytogenetic technics which are useful in such an identification in situ hybridisation is a new technic very helpful in some cases, especially iso p18.
我们报告了在马赛医学遗传学中心检查的23例小额外染色体病例。遗传咨询取决于额外染色体物质的来源。在有助于此类鉴定的不同细胞遗传学技术中，原位杂交是一种新技术，在某些情况下非常有帮助，尤其是等臂p18。
