Nonmosaic trisomy involving 19p13.3p13.2 is a very uncommon abnormality. At present, only 12 cases with this genetic condition have been reported in the literature. However, the size of the trisomic fragment is heterogeneous and thus, the clinical spectrum is variable. Herein, we report the clinical and cytogenetic characterization of a 5-year-old boy with nonmosaic trisomy 19p13.3p13.2 (7.38 Mb), generated by a derivative Y chromosome resulting from a de novo unbalanced translocation t(Y;19)(q12;p13.2). We demonstrated the integrity of the euchromatic regions in the abnormal Y chromosome to confirm the pure trisomy 19p. Our patient shares some clinical features described in other reported patients with pure trisomy 19p, such as craniofacial anomalies, developmental delay, and heart defects. Different to previous reports, our case exhibits frontal pachygyria and polymicrogyria. These additional features contribute to further delineate the clinical spectrum of trisomy 19p13.3p13.2.

Interstitial 1p deletions are rare events. Very few cases of 1p31.1p31.3 deletions characterized by variable phenotypes have been reported. No clear genotype-phenotype correlation has been determined yet. We present a child with a de novo interstitial 1p31.1p31.3 deletion, identified by array CGH, associated with intellectual disability and severe language impairment. The deleted region contains 20 OMIM genes, but we focused on GADD45A (MIM 126335; growth arrest- and DNA damage-inducible gene), LRRC7 (MIM 614453; leucine-rich repeat-containing protein 7), and NEGR1 (MIM 613173; neuronal growth regulator 1). We discuss whether these genes play a role in determining the phenotype of our patient in order to investigate the possibility of a genotype-phenotype correlation.

Supernumerary ring chromosomes (SRC) are usually derived from regions adjacent to the centromere. Their identification may be challenging, particularly in case of low mosaicism. Here, we report on a patient who was referred for major in utero growth retardation, severe developmental delay, facial dysmorphism, cleft palate, and hypospadias. The karyotype showed a small SRC in mosaic. The combination of FISH, M-FISH and array-CGH was necessary for a complete characterization of this SRC. M-FISH revealed that the SRC originated from chromosome 7. Array-CGH performed with a 400K oligonucleotide array showed a gain in region 7q22.1q31.1 present in low mosaic. This result was confirmed by FISH using BAC probes specific for chromosome 7. The SRC was a neocentric ring derived from 7q22.1q31.1 and was found in only 8% of the cells. This is the first patient carrying a mosaic neocentric SRC derived from the long arm of chromosome 7. Our study emphasizes the need to combine different techniques and to use adapted bioinformatic tools for low-mosaicism marker identification. It also contributes to the delineation of the partial trisomy 7q phenotype.
