Partial trisomy of chromosome 10 inherited from a carrier father.
Partial trisomy of chromosome 10q is a very rare condition with only four cases having been reported int he literature. This report describes a neonate with symmetric growth retardation and multiple dysmorphic features, in whom G-banded chromosomal analysis revealed a partial trisomy of chromosome 10q (q2.4-q ter). The father was diagnosed as a carrier of a balanced translocation with a karyotype of 46, XY t(10.3) (q2.4L : pter). In patients with a bad obstetric history, genetic counselling prior to a new conception cna aid in early prenatal diagnosis of fetuses with recurrent chromosomal abnormalities by means of fetal tissue sampling.
