Muellerian aplasia associated with ring chromosome 8p12q12 mosaicism.

We report on a woman with Muellerian aplasia, renal and skeletal anomalies, and minor dysmorphic signs. Conventional cytogenetic analysis revealed mosaicism for a small supernumerary, undefinable ring chromosome. Chromosome microdissection and reverse painting demonstrated that this marker contained pericentric material from chromosome 8 (8p12q12). Thus, we identified a Muellerian aplasia phenotype with partial trisomy 8 mosaicism.
