Ambiguous genitalia, known to be associated with sex chromosome disorders, may also be seen with autosomal chromosome anomalies. Herein, we report a case with ambiguous genitalia and ring chromosome 13. Ring chromosome 13 is a rare genetic anomaly in which the loss of genetic material determines the clinical spectrum.

BACKGROUND Ambiguous genitalia are a major cause of parental anxiety and can create social problems if not properly managed. Diagnosis and management can however be challenging. The aim of this study is to highlight some of the challenges in management of ambiguous genitalia in our environment. PATIENTS AND METHODS All cases of ambiguous genitalia managed at the Paediatric surgical unit of th...

Ring chromosome is a rare chromosomal abnormality. We report a case of ring chromosome 13 associated with ambiguous genitalia. Karyotype is the important investigation in the evaluation of a case with ambiguous genitalia and chromosomal analysis should not be limited to only presence of X and Y chromosomes.

Background: X-linked lissencephaly with ambiguous genitalia (XLAG) is a recently described genetic disorder, in which patients present with lissencephaly, agenesis of the corpus callosum, refractory epilepsy of neonatal onset, acquired microcephaly, and male genotype with ambiguous genitalia. XLAG is responsible for a severe neurological disorder of neonatal onset in boys. A gyration defect con...
