Apart from the correlation of about one third of the sSMC cases with a specific clinical picture, i.e. the i(18p), der(22), i(12p) (Pallister Killian syndrome) and inv dup(22) (cat-eye) syndromes, most of the remaining sSMC have not yet been correlated with clinical syndromes.

As such, these cases highlight the fact that tetrasomy 12p [i(12p)] and Pallister-Killian syndrome are not synonymous, although this combination of genotype and phenotype is often seen.

New molecular cytogenetic techniques array comparative genomic hybridization and fluorescence in-situ hybridization in association with conventional karyotype are pivotal innovative tools to search for chromosomic anomalies and for a complete prenatal diagnosis, especially in cases such as PKS where array comparative genomic hybridization analysis alone could not show mosaicism of i(12p).

Thus, the diagnosis of Pallister-Killian Syndrome (PKS) is confirmed by mosaicism of i(12p), that is, the affected patients exhibit tissue-specific mosaicism, with the abnormal karyotype expression in limited lymphocytes, but marked in fibroblasts.

To ascertain the epigenomic features, i.e., the methylation, non-coding RNA, and gene expression patterns, associated with gain of i(12p) in Pallister-Killian syndrome (PKS), we investigated single cell clones, harboring either disomy 12 or tetrasomy 12p, from a patient with PKS.
