Epithelial to mesenchymal transition (EMT) is a cellular phenotype switching phenomenon which occurs during normal development and is proposed to promote tumour cell invasive capabilities during tumour progression. Invasive lobular carcinoma (ILC) is a histological special type of breast cancer with a peculiar aetiology - the tumour cells display an invasive growth pattern, with detached, single cells or single files of cells, and a canonical feature is the loss of E-cadherin expression. These characteristics are indicative of an EMT or at the very least that they represent some plasticity between phenotypes.

The contactin-associated protein-like 2 (CNTNAP2) gene is highly expressed in the frontal lobe circuits in the developing human brain. Mutations in this gene have been associated with several neurodevelopmental disorders such as autism and specific language impairment. Here we describe a 450 kb deletion within the CNTNAP2 gene that is maternally inherited in two male siblings, but with a variable clinical phenotype.

This report is of a patient with pure trisomy of 15q24-qter who presents with the rare Ebstein anomaly and a previously unreported skeletal anomaly. Chromosome microarray analysis allowed high-resolution identification of the extent of the trisomy and provided a means of achieving higher-resolution breakpoint data. The phenotypic expression of unbalanced chromosomal regions is a complex phenomenon, and fine mapping of the involved region, as described here, is only a first step on the path to its full understanding.
