title: Brief clinical report: ring-11 chromosome: phenotype-karyotype correlation with deletions of 11q.
abstract: The cytogenetic evaluation of a female infant with congenital anomalies led to the identification of the second reported case of a ring-11 chromosome. Unlike the previously described case, in which the patient had only minimal clinical findings and no demonstrable loss of material from the ring, our patient had numerous anomalies that were associated with a substantial deficiency of 11q material. The different phenotypes in these two cases represent variation in the amount and location of the chromosomal material lost during the genesis of the ring. The manifestations of this patient and the deletion of region q24 leads to qter from the ring-11 identify a specific chromosome deletion syndrome referred to as del (11q) syndrome.
