A case of partial 9q trisomy.

Partial trisomy 9q due to maternal 9q 17q translocation.

Partial Trisomy 9q is a unique chromosomal anomaly with a distinctive phenotype. Only 5 cases have been reported in the literature till now. A large family with four affected children was studied in detail and was compared with the five previously reported cases. Determination of this novel balanced translocation in their family had helped us to offer prenatal diagnosis. This presentation is un...

Molecular cytogenetic characterisation of partial trisomy 9q in a case with pyloric stenosis and a review.

Partial trisomy 9q represents a rare and heterogeneous group of chromosomal aberrations characterised by various clinical features including pyloric stenosis. Here, we describe the case of a 1 year old female patient with different dysmorphic features including pyloric stenosis and prenatally detected partial trisomy 9q. This partial trisomy 9q has been analysed in detail to determine the size ...

A third case of de novo partial trisomy 4p.

Interestingly, the previously reported patient with a different but overlapping deletion of chromosome 12 long arm (q13.3-q21.1) and the subject of this report have only a few features in common (table). The deletion in each includes the portion 12q13.3 to q21. 1. It is unclear whether the small difference in the portion of 12q deleted accounts for the fact that they do not resemble each other ...

Partial trisomy 12q: report of a case and review.

A malformed male infant with pure partial trisomy 12q (q24.1 leads to qter), resulting from an unbalanced segregation of a paternal balanced translocation t(2;12)(q37;q24.1), is described. The cytogenetic and clinical abnormalities of the proband are compared with those of four previously reported cases of partial trisomy 12q, two of which also appear to have pure trisomy of segment 12q24.1 lea...
