Ring chromosome 13 with loss of the region D13S317-D13S285: phenotypic overlap with XK syndrome

Am J Med Genet. 1997 Oct 31;72(3):319-23.

Abstract

We report on a patient with a multiple congenital abnormalities/mental retardation (MCA/MR) syndrome including facial abnormalities, agenesis of the corpus callosum, heart defect, 1st ray anomalies of the upper limb, and ambiguous genitalia, whose phenotype overlaps a previous description of XK syndrome. The patient has a ring chromosome (13) with deletion 13q32-qter. Molecular analysis demonstrated loss of the region from D13S317 to D13S285 and a paternal origin of the anomaly.
