Popis: From year 1981 throughout 1 993 we have performed 1 473 caryotipes in patients aged 0 to 15 years. Referencediagnosis were Down's syndrome [30,8%), multiple malformations (19,1%), psychomoto r retardation (10,5%), Turner'ssyndrome 18%), abnormal sexual developmeni (7,6%), short stature (7,1%), speech development disturbances (2%) andmiscelaneous syndromes (14,9%). The efficiency of the investigation for chromosomal abnormalities varied accordinglyto clinical diagnosis: Down's syndrome (94.0%), multiple malformations (24.8%), psychomolor retardation (13.4%),Turner s syndrome [55.6%), abnormal sexual development (T 3.4%), speech disturbances [10.0%) and other syndromes[9.1 %). Chromosomal study allows confirmation of clinically suspected cases of chromosomal anomalies or -if normal- itpromotes ihe search of non chromosomal etiologies in apparently similar phenotypes, and it represents an importantcontribution to genetic counsel for affected families.(Keywords: Chromosomes, human, abnormalities, cytogenetics, kariotyping.)
