Five cases with different abnormalities of chromosome 18 are described: one case with trisomy 18, two cases with ring 18, one case with partial trisomy 18q and one case with a mosaic 18p-/iso 18q. The karyotypes of the parents were normal. Cytogenetic analysis was performed on PHA stimulated blood lymphocytes. GTG, QFQ,
MTX
banding techniques were used. Karyotype-phenotype correlations are made. All patients present mental retardation,
hypotonia
and facial dismorphisms. The different degree of mental retardation and the clinical signs are in relation to the different size of deletions or trisomies of the short or long arm of chromosome 18. In the case with mosaicism 18p-/iso18q the phenotype is determined from the chromosomal abnormality more frequent in the cells (18p-).
