The 11q- syndrome with mosaic partial deletion of 11q.

A female child with mosaic partial deletion of 11q is reported. At 1 month of age she was presented with cogenital glaucoma, trigonocephaly and multiple minor anomalies. She exhibited growth retardation and the typical phenotype of 11q- syndrome. G-banding analysis failed to show any abnormality, although subsequent high resolution banding revealed the abnormal karyotype 46,XX,del(11)(q23.3 q24.2)/46,XX,del(11)(q23.3 q25). This case is a second case of mosaic 11q- syndrome and her karyotype suggests that the region of 11q23.3-11q24.2 is critical in 11q-syndrome. Congenital glaucoma has never been reported as a complication of 11q- syndrome.
