Background: Terminal deletions of chromosome 15q are associated with different degrees of pre- and post-natal growth failure, dysmorphic features, functional impairments and congenital anomalies. Although monosomies of 15q26 do not represent a classical contiguous gene syndrome, candidate genes for selected features have been identified. Short stature is referred to deletions of the IGF1-R gene, located on 15q26.3. We demonstrate evidence of phenotype comparable with 15q26 mon...

MOPD is known to be caused by homozygous loss-of-function mutations in a specific gene, PCNT. Both intra- and interfamilial clinical variability (even for the same variant) have been frequently observed, which makes it difficult to infer a genotype–phenotype correlation. Pericentrin (PCTN) is a structural protein expressed in the centrosome that plays a fundamental role in anchoring protein complexes, regulating mitotic cycle and thus cell proliferation. High levels of m...
